If it were mine, I would check the back meticulously for splinters and if clean go to a low, say 3” brace height. I would exercise the limbs a lot at half draw the. Going into full draw @ 3” brace height. At that point I’d go to a 6” brace and do the same as above. If nothing clicks, pops, or bangs it should be shootable. Most folks tiller to 28”, I would take care to not draw past that at all. Hope it’s a shooter for you.
