So just got a Rx7 ultra set at 75lbs and shooting 30in arrows. I currently have axis 300 spine from my older setup but wanted to order new arrows and wasn't sure if i should go up in spine? I shoot a 75grain brass insert with 100grain broadhead and was going to run a 4 flech aae max stealths.

you need to check calculator on the internet there are many websites. i found today 1 vat calculator website that is doing great.
