Arthur,

Your arguments are probably the best, especially if we consider the average hunter. My problem (well, not really a problem), is that I can easily tune my fixed blade broadheads to group with my field tips. Put me at 30 yards with my 100 grain Muzzys on a 300 grain shaft and I can't shoot a group with my broadheads, because I'd likely ruin the previous arrow with the next shot. <img src=icon_smile_wink.gif border=0 align=middle>

I will say that if I was advising a person who was having problems with tuning their broadheads, it would be to shoot a long ATA like you, heavy arrows, high brace height, feathers, round wheels, and 2 bladed cut on contact broadheads.
