I have recently set up a Mathews MR5 with 80 lb limbs for Elk hunting. (Please note I am dedicated to fitness and strength training, I am capable of accurately shooting this bow and would like to please focus this thread on the question of arrow set up, thank you in advance) I have gotten the 6mm Easton Axis 10.2 gpi 300 spine arrows to shoot well out of it with 125 grain heads for a total arrow weight of 478 grains. This set up is at 328 FPS. I like the advantage of a flatter trajectory for longer range hunting with more forgiveness on judging yardage while maintaining high KE. Would it be beneficial to try a lighter gpi arrow and use a weighted insert to increase FOC while maintaining similar overall weight? If so what lighter GPI arrow would be strong enough spine to support this set up? Thank you

Im shooting Beman Speed 300's which I believe are under 9 GPI and weigh a little over 400 grains with 4 fletch, a wrap, and 100 grain head. Shoot awesome and havent had a problem with penetration. I like the little bit of less pin gap
