You are so right, Greg. I can get about 90yds with my 7i half swing. A full swing (or whatever else I can muster) adds at most another 20yds to that. I've been practising for months and I'm still stuck there.

I might have misunderstood some things here. I thought the purpose of starting the downswing with the legs then hips then shoulders then arms was precisely to have the lower body outrace the upper body so that there is a lot of uncoiling power for impact. I've been trying to rotate the hips and then body and lastly let the arms catch up for that extra power. Is that wrong?
