I have been shooting Beman ICS Bowhunters for a while and overall been a great arrow. I have thought about trying those Easton Flatline arrows. You can increase your spine and decrease arrow weight. I am shooting an Invasion looking to go ahead and max it out to 70lbs at a 26 in draw. The bemans I shot were 400 spine. My arrows are short roughly 24.5 inches. Should I stay with the 400s or possibly go to a 340 spine? I know shorter arrows you do not need to increase the spine as much as a longer arrow. I figured with the increased poundage of 70 lbs that it would not hurt to increase the spine a little. Beman ICS Bowhunters (400s) 8.4 gpi) vs. Easton Flatline (400s) 7.3 gpi)? Im open to any other arrow suggestions for hunting.
