bentpole,I'm not exactly sure how long my current arrows are.I think 31".I'll bare shaft them first before I cut any off.I read somewhere that the Shrews are cut 1/8" before center and since my ACS is cut 3/16" past center,the arrows may work just fine.I was thinking that the extra 5# would make a big difference but the center cut in the risermakes a big difference as far as arrow spine is concerned.I've never shot a bow that wasn't cut past center.I've heard that they are harder to tune.
