Do draw drivers work?
My observations of all draw based clubs: Putting discretionary weight on the inside of the clubhead will promote more clubhead rotation because the toe of the club will be lighter than the heel. While there is no club out there that make you hit the ball straight, this will help some players. It is my opinion that a player who slices the ball because their clubface is open at impact will benefit from this design if their swing path is correct. However, I could see the player that cuts across the ball big time actually hitting pulls or pull hooks with this type of design. This is because the weight distribution will help the player rotate the clubhead so that it is square to the path of the club, which is already moving left of the target (for a right handed player).
