I had emailed him awhile back and asked for some to try. Image my surprize when today in the mail box was a package with two shooters and one tester for clearance of the rest. So i tested and determined that they would clear everything.

Screwed on a four bladed muzzy and let it rip. Arrow flight is good and they are accurate. Ran out of daylite. tomorrow I will also test at a longer range and compare to field tips and other things. Looks like a very workable soluation to broadhead tuning.
