I bought a new (used) 2008.5 Elite GT500 - 28.5" - 60 to 70 lbs. My current arrows are 27" GT pro hunters 7595 with 100 gr insert/100 gr tip, blazers and standard nocks. D-loop and peep. My question is for the software guys. For optimal spine, up to what poundage can I shoot these arrows through this bow?
