RE: H & X Nock what's the difference
Xnocks fit the shafts that use HIT inserts like the EastonAxis and Beman MFX.
H nocks fit the Easton Epic shafts.
Gold tip arrows use Gold Tip nocks or "aftermarket" nocks made specifically to fit Gold Tip shafts. Gold tips inside diameter is slightly larger than the standard Beman, Easton, Carbon Express, etc... etc...
