well congrats, and I love lighted nocks too, they at times make a hard job easier
I use easton's , have had good luck with them for my X box, and I once left on on after shooting a deer, and the darn thing stayed
lighted up for over a week straight?? I left it go to see how long it would last, and then after so long forgot about it, but was about 8+ days before it went out!, that impressed me!, using for target practice, and hunting, I get 3+ yrs out of batteries too!
