Man you guys are starting to scare me. The last two dozen arrows I've bought have been CX300's.

If you want to see some scary arrows check out the PSE line, although I heard they re-engineered them. I had Terminator Hunters (I think that what they were called, but I'm not for sure because I threw them in the trash) that I bought from a closeout of last years stuff (2003). When I was shooting at hay bails at the archery club, on more than one occasion, I had nocks fly off on impact. When I inspected the arrow I would see a hair line fracture right where the nock attaches.
