if you hit in the heart or lungs it doesn't matter if it is a 2 blade, 3 blade or 4 blade. it isn't going to go to far. I have only used 3 blade 125 muzzy's for about 6 years and they do the job great.I have taken down 8 whitetail and allbut one have dropped within40 yards the one i hit a little high and he went 100 yards.This year I got my new Bowtech and am shooting 3 blade 100's and i can't wait to see what it can do. I guess i just like the 3 blade because I can line the blades up with my fletchings and when i do that it seems like the broadheadsfly just like a field point.
