Great shafts for the money. I shoot the 2016s. Wish they made them in 2117 or 2018 for my slightly heavier bows.
I also like that they take glue-on nocks only. With glue-on nocks, the nock can't rotate-- so the orientation of the feathers stays constant. That way, if I just need to replace a single feather, the new feather is aligned properly relative to the other feathers. On my arrows that use push-in nocks, I have a lot more trouble replacing one or two feathers and having them come out with nice 120-degree spacing (I do 3-fletch).
