The Cobra OPTM X and the Callaway Quantum Max are close relatives on paper. Both are 460cc players distance drivers with adjustable hosels, both are tagged for high launch, and both ship with the Fujikura Ventus Blue 6 in stiff. What separates them is fitting range and price. The Quantum Max offers three lofts, 9°, 10.5° and 12°, and adds a Fujikura Ventus Blue 5 in regular as a second stock shaft. The OPTM X stops at two lofts, 9° and 10.5°, with one stock shaft. That makes the Quantum Max the easier fit for a golfer who needs 12° or a regular flex without going to a custom order. The OPTM X suits a player who already knows a stiff Ventus Blue 6 at 9° or 10.5° works, and would rather save $100.
The Cobra OPTM X is the pick if the stock spec fits you, because it costs $549 against $649 for the Quantum Max and gives up nothing in head size, adjustability or launch profile. Choose the Callaway Quantum Max if you need the 12° head, want a regular flex out of the box, or value having more stock options before spending on a custom shaft. Feel and ball flight remain a fitting question a spec sheet cannot settle.
