Thanks for all the leads. I am not the original owner which is why I need a different cam. My Mathews dealer sells everything at msrp.I am willing to pay more for a good proshop but I'm not willing to get raped. Yes, I know he has overhead and is a small dealer... but you never get a break of any kind in there. And the setup they do on new bows isn't up to my expectations. However I do like them in there and I keep going back. The next closest Mathews dealer to me is a real winner... he was trying to sell me an XT and said that "even though the XT is a little slower it holds its speed much longer down range than the standard switchback". I wonder what Isaac Newton would say about that? [:@]
