- +You consistently miss right — push, slice, or push-fade
- +You want automatic face-closing without changing your swing
- +You've been told in a fitting you need draw-bias weighting
- +You want the most aggressive slice correction in the OPTM lineup
- +Your handicap is 15+ and keeping the ball in play is the priority
- +Your miss is tight or random (sometimes left, sometimes right)
- +You play a neutral ball flight or a slight draw
- +You want max forgiveness without locking in a directional bias
- +Your slice is mild (5–10 yards) rather than severe (20+ yards)
- +You want Cobra's highest MOI head without fixed draw bias
Both drivers are built for the same goal — keeping the ball in play — but they take different paths. The Max-D assumes your miss is directional (right) and corrects it mechanically. The Max-K assumes your miss is positional (off-center) and absorbs it with MOI. If your miss is both — a slice that also catches the toe — the Max-D addresses the shape and the Max-K addresses the contact. Most golfers with a significant slice should start with the Max-D.

Head to Head
Weight Design and CG
Edge: Depends on your missOPTM Max-D
The OPTM Max-D's defining feature is a fixed 11g heel weight — the heaviest internal bias weight Cobra has ever put in a driver at this position. This weight sits heel-ward of center, shifting the CG toward the heel and effectively pre-rotating the face toward closed before you even start your downswing. The result: the face arrives at impact more closed than it would on a neutral head, which for a golfer who fights an open face through impact translates directly into a straighter or right-to-left ball flight. You cannot move this weight — it is permanent, and that permanence is the point.
OPTM Max-K
The OPTM Max-K distributes its weight around the perimeter of the head, pushing as much mass as possible to the extremities to maximize MOI. Unlike the Max-D, there is no heel bias — the CG sits in a rear/center position that resists twisting on all off-center hits equally: heel, toe, high, and low. For a golfer whose miss is tight and random rather than directionally consistent, this neutral high-MOI setup is more useful than a fixed heel bias that only helps one kind of miss.
Ball Flight
Edge: OPTM Max-D (slice correction) · OPTM Max-K (straight, neutral)OPTM Max-D
The OPTM Max-D launches high and with mid-high spin, and the heel weighting actively promotes a right-to-left ball flight. In practical terms: a golfer who hits a 20-yard slice with a neutral driver will typically hit a 10-yard fade or a straight shot with the Max-D, and a golfer with a 10-yard fade may start hitting a gentle draw. This is not a subtle bias — the 11g heel weight is significant enough that you will feel the face-closing effect even on shots where you're not thinking about it. For someone with a slice, that is exactly what they want.
OPTM Max-K
The OPTM Max-K produces a neutral to very slight draw bias ball flight — not from heel weighting but from the rear CG placement, which naturally helps launch the ball slightly higher with a more consistent face angle at impact. There is no deliberate draw promotion in the Max-K's design. For a golfer who already plays a draw, it will support that shape without exaggerating it. For a golfer who plays a slight fade, the Max-K will not fight that tendency — it simply minimizes the damage when you don't quite catch the center.
Who Should Buy the OPTM Max-D
Edge: OPTM Max-DOPTM Max-D
The OPTM Max-D is built for one golfer: the player who consistently misses right. If your stock miss is a push-slice — ball starts right of target and curves further right — the Max-D directly addresses the root cause by closing the face at impact. The fixed heel weight is not an adjustment you dial in; it is baked into the engineering. Combined with the FutureFit33 hosel's most upright settings, the Max-D gives you more ways to fight a right miss than any other driver in the OPTM lineup. If right is your problem, this is your fix.
OPTM Max-K
For a straight hitter or draw player, the Max-D is the wrong choice. The fixed heel weighting will close the face too aggressively, producing a pull-draw or even a hook for a player who doesn't need the correction. The Max-K is the right max-forgiveness pick for golfers who want pure stability without directional bias — it helps on mishits without locking you into a flight shape you don't need.
Who Should Buy the OPTM Max-K
Edge: OPTM Max-KOPTM Max-D
A golfer who has corrected their slice through a lesson or fitting change and no longer needs aggressive draw promotion can end up fighting the Max-D's heel bias. If your game is improving and your miss is tightening, the Max-D's fixed weighting can become a hindrance rather than a help. At that point, moving to the Max-K or even the OPTM X preserves the forgiveness you want while giving you back directional control.
OPTM Max-K
The OPTM Max-K is the right choice for golfers who miss left and right equally, whose ball flight is relatively neutral, or who want the maximum MOI in the OPTM lineup without committing to a directional bias. It is also the better fit for a golfer whose slice is mild — a 5-yard fade rather than a 25-yard banana — since the Max-D's aggressive heel weighting may overcorrect a mild miss. When in doubt about which max-forgiveness head to choose, the Max-K is the safer default.
Verdict: Pick Your Miss, Then Pick Your Driver
Edge: Right miss → Max-D · Neutral miss → Max-KOPTM Max-D
The OPTM Max-D does one thing extremely well: it closes the face. If you have a right miss and you are tired of losing balls in the right rough, the Max-D will make your round meaningfully easier. Do not buy it hoping to "dial it down" — the heel weighting is fixed. Buy it because you need face-closing correction, and you want it on every swing without having to think about it.
OPTM Max-K
The OPTM Max-K is the more versatile max-forgiveness head. It suits a broader range of miss patterns, does not lock you into any shot shape, and has the highest MOI in the lineup for pure stability. If you are not sure which Cobra max-forgiveness driver to buy, start here. You can always add draw correction through a shaft or hosel adjustment; you cannot reduce the Max-D's heel weighting once you have committed to it.

Frequently Asked Questions
What is the difference between the Cobra OPTM Max-D and OPTM Max-K?
The OPTM Max-D is a draw-bias driver with a fixed 11g heel weight specifically positioned to close the face through impact and promote a right-to-left ball flight. It is built for golfers who fight a slice. The OPTM Max-K is a neutral max-forgiveness driver with the highest MOI in the OPTM lineup — its rear/perimeter CG minimizes twisting on off-center hits without promoting any particular shot shape. Both are maximum-forgiveness heads at the same price; the choice is whether you need slice correction or pure stability.
Should I buy the OPTM Max-D or OPTM Max-K if I slice the ball?
If you slice consistently and right is your standard miss, buy the OPTM Max-D. The fixed 11g heel weight is engineered specifically to close the face at impact, not just reduce the severity of a slice but actively correct it. If your miss is more of a slight fade than a hard slice, or if you occasionally also miss left, the OPTM Max-K's neutral forgiveness profile will serve you better without locking you into a draw bias.
Can I use the OPTM Max-D if I don't slice?
Technically yes, but it is not the right club for a neutral or draw-bias player. The fixed heel weighting will push your ball flight further left than you intend, reducing your ability to aim at the center of the fairway. The OPTM Max-D is purpose-built for golfers who need that face-closing assist. For a straight hitter or slight draw player, the OPTM Max-K is the better max-forgiveness choice.
Is the OPTM Max-K more forgiving than the OPTM Max-D?
In terms of pure MOI, yes — the Max-K has a slightly higher MOI because its weight is positioned for maximum perimeter weighting rather than heel bias. However, for a golfer who slices, the Max-D is functionally 'more forgiving' because it keeps the ball on the fairway despite the same swing. Forgiveness means different things: the Max-K gives you directional stability, the Max-D gives you slice correction. Pick based on your miss.
What is the weight setup in the Cobra OPTM Max-D?
The OPTM Max-D has a fixed 11g heel weight that is positioned to promote draw ball flight by biasing the CG toward the heel. This closes the face more aggressively at impact compared to a neutral head. The FutureFit33 hosel still allows 33 loft and lie settings, and POI face technology is present on both the Max-D and Max-K. The key difference is that the Max-D's internal weighting cannot be moved — it is permanently engineered for draw promotion.
