Dawg, I started using them last year, but its not that same brand and I think the're the greatest. The nock I use looks just like a regular nock and is inserted into the shaft as opposed to a regular nock that is glued to the outside of a shaft. I won't go back to a regular nock. I am always tring something new and expermenting, try it a few arrows and give it a try and find out. Good luck and let us know the results, Bobby

P.S. Dave, how do you figure that happened and why?
