i have a question regarding getting the hands in position on the downswing. i have a dvd called 'explosive golf' by a gsed guy mike jacobs i think. he says the hands are just like vice clamps that hold the club and the body core is what brings everything back to place. i thought i read here though that the hands still guide the downswing. also, if that is the case, where does pulling the left hand/arm come into play? what what am i missing? thanks
