Been shooting the GT's for a long time. When I get them now, I switch out the nocks with Easton Super 3-D nocks. I only started doing this after the "problems" they had and report of, a few years back or whatever. I never personally had a problem with ANY GT nock, when I used to shoot the ones that came with the shafts. These days, I continue to replace the stock GT nocks with the Easton nocks simply because I like them a little better. They are a tad longer and stick out past the string a bit more when nocked....and I just like that.
