Couple thousand!? You better start soon....
I just played with them last night next to other glue on bohning nocks, marcos, easton, CX and a few other carbon nocks, Arrow dynamics, and Old Mercury speed nocks (pretty much what I have laying around) and back to back every time they just seem to nock themselves before I even get the urge to look down. Nirk Nocks are my next choice. I actually thought these legends were nirks until just a few days ago.
I really want to like the mercury speed nocks, but the ends seem too sharp that they dont rotate on the string as easy when nocking out of alignment.
