I've been considering the C721 driver and play a few other Tour Edge clubs that are as good or better than major brands for me. I've watched a few good reviews on youtube. Anyway, sometimes certain clubs just won't work for us no matter how hard we try. I'll buy a different shaft just to make sure that's not the problem. I usually go the inexpensive route like Diamond Tour golf where I've bought several cheaper shafts just to see if that's the problem...God luck!
