I agree with the others, light arrows are ok of you are shooting a really efficient set up, but once

With out getting into a mess like the KE/momentum question. How are youth hunters taking down big game such as elk when pulling less than 50#? I am shotting a Browning Rage1 with a draw wieght of 70# andarrows that weigh 321.85g with a speed of 242fps. Even if I change to a heavier arrow the most KE I can get with out zeroing or loosing to much fps is 41.86ft lbs, the heavier arrows slow the bow down to much. Oh by the way I have a 25" draw. Just wondering I plan on going elk hunting and according to a chart I found on the Gold Tip site to take an elk it requires 50ft lbs.
Please don't take offense, but my 50lb bow generates about the same KE as your setup does at 70. Certainly the equipment makes a difference.
