RE: Arrow rotation, is it important?
I tried the turbo nock earlier this year and did not like them much. When I tried to tune with them, I ended up with the nock about 5/8" above 90 degrees. This was unexecptable to me and I adjusted the tiller and got the nock back to about 3/8th over 90. But then, I wasn' t happy with my tiller and I was having a difficult time keeping the pins on target without fighting the bow. There were some other problems, that I had with them as well. I went back to my normal four vaned arrows and all was good again. Just my experience with them.
