I shot 3 does with lumenoks this last fall out of Easton Axis shafts. All 3 stayed lit the whole way, even after pass thrus. Its never been so easy to find an arrow, its the greatest invention in archery hunting if you ask me. I probably won't mess around with building my own, just stick to the lumenoks! One evening me an a buddy were driving around an there were tons of jackrabbits running around, so we played a lil game of shooting jackrabbits with my lumenoked arrow with Muzzy MX4s, it was pitch black out and it was like shooting them with a laser beam!
