As far as spine goes, I'm shooting a '05 allegiance at 70lbs, 27"dl, ACC 3-49, 390 at 27 5/8". Sounds right no?
The Binary cams tend to like a softer spine in my experience, and while 3-49's are close and shouldn't cause you a problem in tuning. I would probably have tried a 3-39. I shot 27.5"CX Maxima 250's out of my 70# Allegiance and those things flew awesome.
