Cobra OPTM MAX-K Driver belts which are uniquely designed forBoasting a staggering MOI of 13K, the oversized Max K is Cobra's most forgiving driver and the most stable driver in golf. MOI, or "moment of inertia", is the term the golf industry uses to measure a club's stability and forgiveness. When a mishit occurs, the club head rotates around the ball, causing the face to twist open and push a shot offline. The higher the MOI, the more stable the club is, and the more resistant it is to twisting at impact.
