I searched but couldnt find anything on here about the FOB, This is the first Ive heard of them wondering what everyones thoughts were? have you or someone you know used them? http://www.starrflight.com/how-fobs-work/ a couple more interesting videos http://www.starrflight.com/category/videos/
I tried them and didn't like them. I couldn't ever get them to stop hitting my fall away rest. Also they messed with my anchor point.
They're also, at least in the first link, Only comparing it to 4 or 5" vanes not shorter blazers. Wonder how it compares to them.
Heres a few "home tests" I found Im sure theres a few better ones https://www.youtube.com/watch?v=DZn4FW1csxM https://www.youtube.com/watch?v=DZn4FW1csxM
They are good and do work as designed. I tested using a Vaportrail Limbdriver Pro V and had no clearance issues at all. They work good in a bind. The only complaint I had was some would whistle. Its like many things its really up to what you like. You have to have confidence in your equipment else your done before you get started.
Tried them like others mentioned they mess with my AP, also they make more noise than regular fletching.
I have some. Like others stated, they whistle in flight. They performed very well, but I didn't like the noise and switch to blazer vanes
