RE: Starflight FOBs
I really like the FOBs. I hated fletching arrows, and these things are so easy to use. I like the fact that it forces you to make sure your drop away rest is functioning 100% perfectly. With regular vanes, I had slight contact and never even knew it! With a FOB, any contact is really obvious to say the least. That's a good thing because you know your rest is tuned correctly.
I use the 1" FOBs with a QAD Ultrarest (Hunter) with no problems. As long as you set up the rest properly, and use the OTHER launcher that comes in the package, you should have no problems. There's a ton of info on this subject at archerytalk, too. The founder (Paul Morris) is extremely helpful with getting your rest set up the right way.
By the way, they fly as advertised - terrific!
