Thanks for the replies guys. There is no limb twist or anything like that. One limb just veers off to one side slightly, causing the string to be right of center. It still tracks through the handle but it is definitely off center. This bow is also backed with bamboo, and with the draw weight being so high, the string has been cutting through the bamboo like crazy at the nocks. I tried putting some wood overlays on but the string seems to cut through those too. I'll either have to get some different material like phenolic slabs or horn to do some overlays or maybe even just not cut into the back of the bow where the nock is (after cutting new nocks in the sides)....not sure what i'm going to do there yet.
