Thanks for the reply guys. After someresearch here and on the Mathews site I determined that I need to check idler lean, cam timing,etc. Thanks Elkcrazy8 for the information. I printed everything and will try and find a pro-shop in my area. The guys at the store where I bought the bow make me nervous and some of them know less than I do. I feel I could do the work myself but I don't have a press and the old lady might not be to keen on me adding that to the shop right now. Anyway, I think I will seek some professional assistance and maybe get started off right with a new string from Vapor trail. Thanks again for taking the time to respond with some useful information. I'll let you know how it turns out.
