I shot a 200lbs deer quartering away at 40 yards with a used rage on it. It blow right through and buried in the ground. This is with a 3 blade rage and buy the way I have a 26 inch draw length and pulling 70 lbs. So you do the math on how much Ke I have with a guardian with my draw length an with a 352 grain arrow that moves at 273 buy the way its 61fp of Ke. If I can do that I dont know to many people that would have a problem with one. I used to use muzzys until I did a test on BH I used a muzzy, rage, sidewinder and sonic all 100 grain the sonic and rage penetrated more in to a 2 inch board then the others. Now do the others get the job done yes but with my draw length I want what penetrates the best and after my test out of all of those is rage and sonic.
