RE: Lumenocks...
7point..I'll tell ya I made probably 6-8 of them. They are fun to make, but honestly the cost savings becomes negligable. Screw one up and you've blown your savings. Screw up an arrow with it and you're in the hole! If your doing it for a hobby and to try it, it's fun..but don't do it for the savings.
I'll be looking at Smart Nocks this year.
