Have it checked out throughly. The redline limbs had alot of issues as it is. Check axles, cam/idler bushings, pockets, etc.

If it does have issues, you likely will a difficult time finding replacement parts...at least from Hoyt...original Redline cams are pretty much gone except for some laying around dealers shelves, and I'm sure they have few if any replacement limbs, left. Hoyt rarely keeps parts in stock for more than a couple or 3 years after something is discontinued.
