So update... - played yesterday with this driver and a Bang o matic 6.5 deg with a graman limey that I just picked up locally in a trade with a buddy. Well, I had about 5 drives with the Killer bee and overall pretty impressed. Distance on mishits was pretty good and hit a couple of pretty good drives as well. The XX penley is probably a bit too stiff for me but it's manageable. Sound and feel were great and this is a driver I could easily game if needed. Since it's not worth anything, I'll just keep it and play it from time but for now it will be my gamer for the next few rounds until my Maltby StW2 and Ke4 TC heads arrive. As for the Bang driver, unfortunately the limey x-flex shaft was just a bit too stiff for me. I hit a couple of decent drives but it was tough overall. It's too bad because the shaft feels great and looks even better. The bang was just a fun trade with a buddy and I'm gonna reshaft it with a prolaunch blue 65x shaft - as a high spin/launch shaft this may be a nice compliment with the 6.5 deg head.
One thing for sure, as I have been mostly playing with OEM drivers (ping, tm, callaway) the last few years, I am really enjoying looking down at a compact head. I definitely prefer the smaller looking head and deeper face of the bang.
