can you guys tell me the best way to get a good knock fit on a string I did snd them some and it helped I just dont whant to sand the to much.

IMHO nocks shouldn't ever be altered to obtain correct fit to the serving, rather serving diameter changed to fit the necks. Biggest problem with either sanding nocks and squeezing them together is getting all of the reworked nocks consistent, and remaining true to the centerline of the arrow.
