No. Nobody here uses them, or has even heard of them.... Just jokin around a little man.....They obviously work or most manufactures wouldn't have them as an alternate fletching option.....Instead of just your standard 4" vane, you can get them w/ Blazers now as well. Blazers are probably one of the biggest, fastest growing rages in archery right now.

I can hit a 2" square at 60 and 70 yards w/ Blazers. They work extremely well.
