I am shooting a Trophy Taker Xtreme FC pro mounted to a CST at 28" dl 76.5lbs and 400 Easton Axis arrows cut to 27" at 389gr with 3 helical Blazer vanes. I have the rest tied to the down cable and it is coming up to the highest position in the last 1" of draw. My problem is I am getting contact with the rest from my two hen vanes. I am paper tuned and shooting bullets but still notice contact being made. Any suggestions on how to correct this?
