Needore info. Draw length of the bow. Length of arrow and point weight.
If 29" or less in both counts and assuming a 100gr point you could easily get away with a 400 spine, meaning a GT XT5575. It won't hurt to shoot a 7595, but it's a bit on the stiff side and you won't get quite the speed you would get with the 5575. If you already have the 7595 then give them a try with broadheads (hunting?) to see how they fly.
