haha. last night i was thinking you were probably referrring to backswing. i was talking about unit turn/takeback. from ready position while your are standing in athletic stance facing the net with 2 hands on the racquet. then you do the unit turn (takeback). if you have 2 hands on the racquet your elbow will reach the back first. then at end of unit turn/takeback you do the backswing. that is led w/ the hand as you say. The original issue i was talking about was that OP is in athletic stance then he cocks his wrist back immediately which points his racquet head back and THEN he does the unit turn.
btw, you should watch the virtualtennisacademy vids on ssc. he has 2 of them. one in video instruction and one in articles. they are excellent. the ssc is the motion that locknroll talks about w/ the drum.
fyi all my posts come with an implied "IMHO"
