mobow, you might be onto something here. I'm curious, what would be the proper 78 for a 70lb Ally at 27"draw shooting a 27 5/8" arrow with 100g head? What about those CXs you're unloading? I think I would need 250s not 350s no?
No, you'll want the 350's.....I tried the 250's @ 28".....much too weak.
250s will work just fine. I shot them 2 seasons ago at 70 lbs 26" draw and 27" arrows and they tuned very nice. At a short draw it will stiffen the arrow more. That and a 26" draw was busting out a whoping 284fps. They might not be as good for you with that extra inch.
