Well I called Martin tonight and I believe I talked to Martin. He admitted that a handful of bows with the Tru Arc cams had this occur, due to bearings being improperly installed but that there was no problem with the original Tru Arc cams. I asked him " If there was no problem with the 04 version why would you beef up the part that was cracking on the cams for 2005"? He said he didn't know anything about such a problem existing, and that they changed them for better performance. Further I had nothing to worry about, and that my 2004 Tru Arc cams would be fine. Well I'm still a little concerned. PUG, you seem to know more about this problem than he does, do you agree with his statements? Is there anything I need to be concerned with, or is everything fine with my 04 Tru Arc cams? Is it possible to upgrade now to the Tru Arc+ cams, if they are so much better I wouldn't mind switching now, even if it cost me more money.
