I have some, but I just havn't made myself try them.

I gave some to a buddy of mine and he wasn't impressed. He said the arrow seemed unstable in flight compared to the arrows he was shooting fletched with vanes.

I am going to try them sometime....My initial thought would be if they were that good, a lot more people would be using them. I rarely hear of people shooting them on the forum.

...but, again, I have NOT personal tried them yet.
