The inventor, Nick Snook is my Kung Fu Segung (Grandfather), he taught my instructor (Sifu) here in my home town. He tried forever to get me to try them as much as I do in the industry but alas, they didn't come in a small enough size for my ACC's without removing the nock bushing and I've never had issue with arrow flight with my set up and vane choice, now Blazers, why mess with success...LOL

Per the Turbonock, I've heard a lot of great reviews on them and many won titles using them but like the FOBS, I just don't see the point. I enjoy fletching arrows and I cannot imagine better flight nor groups than I'm currently used to. I believe Nick has since sold the nocks, not sure, haven't seen him in a while, last Christmas when I talked with him I believe he was moving into the New England states, Vermont perhaps.
