I don't know what specifics your bow requires, but I get GT shafts from Wyvern Creations cheapest anywhere I've found. He did glue brass inserts and flat nocks [Excal shooter] for free. He also sells alum moon nocks for a few shafts.
There's a thread on AT right now on how factory plastic moon nocks on Easton/Bemans are crap, fwiw. I use an AZ-EZ fletcher in rh helical on the advice of Danny Miller. My best bench rest group was w/ 2" Blazers, Gt's w/ brass inserts [110 gr] and 100 gr points. 400 gr total weight. Add 9 gr for 4" vanes. It was 1-1.5", 5 shots at 50 yds. Others have done better.
If you get an AZ-EZ, be sure to get the one for alums as the carbon one is for skinny vert carbons, not the 22 series we xbowers use most.
I've had good results w/ 4" duravanes also. There's a vid available on paint cresting w/ spray laquer [only].
Have fun!
