Yes i think i will stick with the firenocks for now.I dont want any unexpected problems if i can help it.Thanks again!Funny this topic came up now! I went through this not long ago with my Nemisis. Shooting the Lumenocs I had one nock break and feel like I was really lucky and really wasn’t sure what happened so I tried another! Sighting in and practicing with broadheads it appears these nocks actually gradually wear and the opening gets deeper as it gets closer to breaking. Like I said this was with a full strength Nemisis. Hope this helps some.
