You said you went to your local Mathews retailer, last year, to have him check the bow. Why not go back to him this year? After all, he didn't try to rip you off and sell you cables and string you didn't need them. Mention this to him and you might be well on the way to building a good relationship (and getting some good deals).
Just don't be like the many morons out there who have someone spend the time to check their stuff over then order from somewhere else just to save a couple of bucks, especially if you don't have a press and will need them installed.
I remember spending hours messing with customers bows only to have them go down the road to save $5.00 (yes that's $5.00, not $50.00). Then they brought the stuff in for me to install, and what would have been done for free if they had purchased from our shop cost them dearly.
