No other nock is in the same league. I am somewhat embarrassed to tell this story but I'm going to drop the ego to prove a point. I shot a deer last year and completly botched the shot off a twig deflection. Arrow ended up sticking in the rear flank of the deer pretty deep, I was sick about it. I stomped every brush pile and grass patch on the property for the 3 days that followed.
Walking back to the truck after an evening hunt 9 days later and I spot a flourescent green light bounding away in a spooked deer that was feeding near my truck and oddly it seemed healthy as the day it was born. Watched it go 150 yds and into the timber shining bright the whole way. Not kidding in the slightest. I hope they never change these nocks, they will be on every arrow I launch from now until the forseeable future.
