Re: good bolts?
The Predator is a very high performance bow. In that case the best accuracy is gonna be with very stiff arrows. I would look at the Carbon Express Blue Streaks, Gold Tip Laser III and IVs, Easton FMJ, Aramid KVs. Cheaper, weaker arrows will work but your best accuracy is gonna come from stiff arrows with the proper wieght forward.
As far as nocks. There is a big differecne between flat and moon nocks. It is safe to shoot a moon nock out of any bow, but it is not safe to shoot a flat nock out of a bow that calls for moon nocks.
The Predator is known to be hard on strings. Inspect them thoroughly for fraying or wear beofre you shoot it. As for the quiver, Arrowhead hear can hook you up in a jiffy.
Best of luck with it and let us know your impressions once you get to some shooting.
I support all hunters, regardless of weapon or technique!
