for what it is worth, grip size can affect the balls flight, to small usually leads to a hook, to large promotes a slice. You can get measured for that also so that your grips match your hands. However this is not the problem with twentyone, sounds like he has a common swing flaw that the less loft of his driver is exposing because his approach to the ball is outside in with a closed clubface leading to low left pull hooks. Have someone that knows the swing look at your swing.
