Well, I wonder what the difference is between a Lumenok X and a regular Lumenok?? I'm asking because I have a regular Lumenok and I also shoot ST Epics but that Lumenok WILL NOT fit into the shafts of the ST's. Lumenok says you can shave the diameter of the lumenok so that it will fit, but at the price of them lumenoks, are they going to replace it if you screw it up??

** Just to update on this. After I posted this, I said what the heck. I took my Lumenok and carefully shaved down the diameter of the nok shaft, using a Dremel Tool. Wasn't real tricky and didn't take long. The trickiest part was getting RIGHT close the the bottom of the nock itself, where shaft meets nock. Once I got that down to a decent size, the Lumenok fit perfect into the ST Epic arrows. Although I haven't shot it yet, I can tell by simply using my fingers to apply slight pressure, that the force of the shot should make it light up. I'll be able to test it more on Sunday.
