The shorty hunters I have weigh 6 grains each, so 24 for4 of them. I also added the wrap to the arrow which puts on some more weight. Oh, the rest I'm shooting a Limb Driver(fall away). I've spun the nocks every which way you want and had no contact or clearance problems. I do however have all mine with the same orientation now, vanes turned to 45 degrees from verticle so you have them pointing up left and right and down left and right.
