Well, I have 4 cam.5 bows, and # 5 is on the way.

I have yet to find one single thing wrong with the new cam & 1/2 system.

I have run probably 5000 arrows through one of my ultratecs, and getting close to that many through my first protec. And I have not had one single problem.

These are beyond a doubt the sweetest shooting rigs Hoyt ever made.
