Suggestion? Buy back your beloved Allegiance!
You could also check out a 60# 29" Jet Black Elite Z28, trade in your 82nd for it....if you no like, Ill find a home for it from there.
I had same problem with my vectrix....i got close but eventually resighted for BHs. In my case though, it was user lack of knowledge...not equipment...Im sure it can get there, but my shooting skills/tuning capabilities wouldnt do it for me this summer. Im talking the groups are maybe 2-3" off max, but still enough for me to resight.
I only practice with BHs from this point forward.... and Ive been fairly accurate....I broke two rage practice tips by stacking arrows. didnt damage shafts, just the heads got mangled when they collided with each other in foam.
