I am shooting my Alligiance at 60lbs, 30" draw, GT 400 UL pros 29.5" 100 grain Muzzys, and G5 montecs( 383grains) ,297fps. This was by far the the most simple bow to tune with broadheads. Field points and broadhaeds hit the same out to 45 at 60yards there is about 1.5- 2" lower with the broadheads.
If the trap door is your favorite rest keep trying it, I would say try another rest I have been using 3D Super Stars for over 12 years with absolute success. Just try another rest. The Allegiance has to be one of the most user freindly tune bows out there.

Best regards
and have a peacful New Year
