quite borderline..were you shooting vanes instead of feathers I'd say def go with 3-49's....

As it is, you could go with a 75 grain tip and feathers and be spined just fine with 3-49's.

Hmm, I thought his reasoning for going to ACC's was for spine consistency. I would go with the 3-49's as well at your draw length and weight. I can shoot 3-49's at my 29.5" draw just fine, not that I own any, but have shot some of my buddys and they fly like darts out of my bow.
