I shoot the 7595 3D Pros cut to 28.5 and fletched with 3 4" feathers. I use 125 grain Stingers. My bow is setup at 65#'s and these arrows fly beautifully. This should be very close to the weight you want and they do pack a PUNCH, especially with those Stingers.

PS Forgot to add, I have used the weedeater string too (when I had 5575's), and it works great.
