I don't like to speak for others, but many of us on here use tied-in nocksets (using simple peep/nock tying thread) with a d-loop tied directly on the serving (one knot on top of the top nockset, one knot below the bottom nockset). As long as you tie the d-loop properly, and use good quality cord (BCY), you shouldn't have any spinning issues. Check Greg/MO's How To thread in the Technical section on tying in nocksets, and d-loops. It's an excellent reference, and should help ease your mind on the setup.
