Dan, thanks for posting those pics. I have an 08 Firecat and have been seriously thinking of buying a TRG/SOS system but have been told it won't work. This really get's my excitement level up (again) as I contacted Martin and even spoke with Joel who told me this system isn't compatible with older bows like mine. After expressing I REALLY wanted to buy this to experiment with it he finally transferred my call to Carly in sales. She confirmed I couldn't buy them through the online store but gave me the name of a pro dealer, saying I could have them order it for me and they'd have it drop-shipped to my house direct. She didn't tell me now much it would cost (didn't know), although Joel estimated it might be in the $45 range.
Seeing your setup is very encouraging. I noticed you even installed a set screw in the exact same location I did to secure the guide rod. Our bows are almost identical, having the same riser, with the only thing really different being your bow has the M-Pro single cam and mine has CAT cams. Have you checked for cam lean, limb tip lean or cable contact with the cam modules during ANY part of the draw cycle? Those are some of the things I was told were the problems with using the TRG on my bow.
Also, if you don't mind, can you tell us how much these parts cost you?
