Bart,
I shot the field tip into the arrow with the broadhead. I had 4 arrows in my hip quiver, 1 stinger and 3 field points. My bow was tuned pretty good but wanted to get my broadheads shooting lights out. I shot the stinger first then the 3 field points. My broadhead was hitting 2 inches right so I adjusted my rest out but groups did not tighten. Finally lowered my rest 1/32 and hocus pocus, robinhood. I unscrewed my broadhead from my robinhood and shoot 3 more groups perfect at 20 yds. And Bart, those are barred feathers not vanes.
