They have been advertising a lot on the various shows..
Appear to have a few advantages..
including no rubber bands or O rings (like the spitfires)..
Any experiences or thoughts on this product.. they look good on paper.

I shoot them and love them. Killed 6 deer over the past 2 seasons with the Grim Reapors. Huge hole, fly great.

Good heads overall. I don't think they are any better than othe quality heads of similar size, but they seem just as good.
