While I was shooting at the Western Classic Trail Shoot in Redding last weekend I stumbled across a new arrow/fletching combination that looks very promising. I bought a dozen to try out and have been shooting them all week. As far as accuracy and consistency goes they are as good as any other carbon arrow I have tried. The slip in fletchings work like a charm and the glueless inserts haven't had any issues at all in any of my bag or broadhead targets yet. The only testing I haven't done yet is pass throughs through material. I will be doing that this weekend.
Broadhead spin-out was excellent and I didn't have to adjust a single one. However, with the set-screw insert you can easily reposition your broadhead if you need to adjust spin-out or like to align your heads with your fletch.
Essentially the rear end of the arrow has four slots cut into it that receive a four-fletch insert, much like tournament darts. There is a metal collar that slides over the area behind the fletch and a standard nock is inserted. The front insert uses a set screw that expands the insert to lock it in. It's a totally glue-less system. The fletches are some sort of super stiff nylon material and they are way tougher than any fletch I have worked with.
These are great arrows for those of us that don't like or want to shoot a drop-away for FOBS. No glue, no hassle re-fletching.
Anyway, check them out at www.megathrustarchery.com . I have no affiliation with them and shelled out $150 for a dozen on my own dime.
