What he said -- bit Zenith(i beleive thats the company) put out an upgraded nock reviever for the bitz that is supposed to be more accurate and easier to fletch short vanes with more helical and offset.
I am getting one of these and was wondering do you have to get different nock recievers for right helical and straight?
Unfortately, your supposed to use different nock recievers for each. I don't myself. I think I have a RW nock reciever and when I fletch, I leave my nocks lose, or most carbons use nocks you can turn. I fletch up like normal and turn my nocks the way I want.
