I shot 27.5" a/c/c's in the 3-71 variety, last year with NO issues. The extra spine is NOT an issue for short range shots....and I liked the extra weight.

If I were going to shoot the same #-age, this fall....I'd have ordered the 3-71's. I'm lowering my #-age and have ordered the 3-49's.

At 70#'s...."I" would shoot 3-71's. Good luck.
