Good to hear it was that easy for you Jim I know what's my bad habit - when I reach the top, I try to hinge my right wrist and by overdoing that, I end up cupping the left wrist. And to my horror (by doing some testing just now), I found out that if I really overdo the hinging of the right wrist, the cupping actually disappears! Well bad news is that it's now ingrained in my swing as a result of doing the same thing for 10 months, and it's really difficult for me to kick that habit now...Plenty of drills and practice swings for me now I guess :P

Good thing is I realise that even though my left wrist is cupped at the top, when I swing down I will uncup the left wrist and end up with a nice flat left wrist and cupped right wrist at impact.

So I'm curious to know, what hosts of problems would a cupped left wrist at the top bring, if at impact it goes back to flat? Is it the swing plane? Power loss? Etc?

Thanks!
