Last year hca was installing there limb bolts with an impact wrench, which caused the problem with there risers. This problem has been adressed from what I have been told. I was also told that there limb vibra-armor has been improved also. I have a good friend that has an HCA dealer ship, and they haven't seen any problems lately. In my opinion, I think they are a super great shooting bow. And I would not be one bit affraid to purchase one, if I wasn't so hung up on the Dartons and the c/p/s system. In fact, I have a best friend that shoots a HCA bow, And it's accuracy and consistancy are unbeatable.
