I own an 05 allegiance , field tips and broadheads hit together . Im useing a Trophy Taker shakey hunter rest . I believe the problem you are haveing is related to the rest you are useing . Trapdoor rests drop very quickly , to fast IMO for proper fixed broadhead flight . The 05 allegiance bows have a massive centershot , which is offset from the center of the grip . This can cause left to right issues , but up and down issues are generaly an easy fix with nockpoint adjustment , if you have tryed this , and thats not the case , I would assume its a rest problem . I have heard of noone with cam timeing issues , or up and down nock travel issues with these bows. I doubt you have missmatched limbs , but its posable . Try another rest .
