just saw this. i am shooting VAP V3 in 600 spine, full length, with 125 grain tips. glad you finally got yours. i thought about going aluminum, but haven't figured out a good place to start with them yet. i think maybe 2013s cut to 30.5 would work for me. i'm running about an 8.75 brace height right now. i've gone all the way up to 9.5, and it didn't seem to effect my impact point from 8.5, so i untwisted back down some and left it there. what weight limbs did you get for yours?
