If it floats your boat......
Bronko - We need every mental advantage we can get as it is all about confidence. If we want to align our blades with our vanes, spin every arrow, sprinkle with foo-foo dust, then let 'er rip! I doubt it has an tremendous effect, but I do the same as Vermont.
I shoot the ST Epic 400 at 70# on an Switchback with Innerloc 3-blade 100 grains (278fps). Every fixed blade BH I have tried shoots different POI than field points, but consistently so. About a month before hunt time, I switch to BH and adjust my sights back with groupings as good as my field tips. I am not concerned about the same POI if I am shooting consistent groups with good arrow flight.
