RE: Those crazy Turbo nocks?!?!?!
Bubba,
The things weigh 50+ grains. My feathers and nock weigh 23gr. That' s just about 30gr moe on the tail end of the shaft. FOC-- you got to be kidding. More like ROC (rear). And you must use a drop away rest. Shoot them through a Whisker Biscuit and see what happens.
