LOL, Flying Beer Cans!

Can I use that?
I don' t shoot any of the all-carbon shafts without uni-bushings, especially Goldtips, because I have found their nocks to be about the worst on the market. They are way too tight on the string, crack the back ends of the shaft w/ that set screw, and as you found are extremely brittle.
Do you use a rest that ends up around the berger button hole when you shoot a release Arthur? I can see you problem with not getting enough length even out of raw shafts with your draw length. If you were using a Golden Key Premier series, or a NAP3000 style that allows for a bit shorter arrow, sizes 3-49 and up are 32" plus. Assuming a 34" draw, even at the berger you can probably get away w/ a 33" arrow, and with the rests I mentioned you can set them back an inch or so w/out getting the hassle of a full blow overdraw.Of course that is, if you were even willing to fork out the dough.
You might also look into the Beman Matrix, which is a less expensive A/C option. They are not an A/C/C IMO but still a step up from most all carbons.
