I use 2 inch Blazers because they seem easier to get to group better than my old 4 inch vane with broadheads. I was said before the reason we can shot them now is because of the drop away rest. We have always known higher profile vanes work best but, couldn't get them to clear the rest. Blazer, high profile vanes and the drop away rest is one ofthe best things to come along in the last 45 year that I have seen for helping good arrow flightwith broadheads.
