The black one has 77lb @ 16" marked on it, while one of the white ones states it is 70lb @16". I'm assuming the 16 inches is the length to latch, and guessing it is measured from the back/centre of the limb/ mounting, or the limb mounting point in the stock?
The black one is in great condition.
The fiberglass on one white one has started to delaminate from the wood core at both the string nock, and close to the stock mounting point. While the fiberglass outer laminate on the other is showing signs of minor splintering.
Thinking of gluing and clamping the delaminations with 24hr epoxy, and maybe running the same glue, or polyester resin into the splintering glass... and then binding entire limb.
Any thoughts appreciated.
