Ever try this swing check/drill

[jfrain2004]

Missed my regular 4 ball on Saturday so slotted in with 3 other guys.  One of them looked like he wouldn't make it past the first tee never mind play a full round.  How wrong was I and even more so when he hit his first ball. I started to notice his pre shot routine and asked him about it.  It didn't involve a practice swing of sorts. Just a full backswing and slowly lowered the club till it was parallel to the ground and then he checked his hips were clear wrists were still cocked,  leading edge of club was almost vertical, club approaching ball slightly on the inside etc.  He would do this twice and 3rd time was go and always produced a crisp strike with a lovely draw. He said his thinking was if you couldn't get your body and club into the right position in slow motion then what chance do you have at full speed.  So I tried it on the range afterwards and it worked like a dream.  Can't wait to hit the fairways next wknd.

Any one ever do this as a drill or part of your pre shot routine. ?
