Having been Bowhunting 48 years I have used many over the years BUT since they came on the market in the 70s I have always used the Rocky Mountain in a 3 blade. I used the Razors mostly & the Premier & now the Ironhead (always 125gr). I have taken Whitetail, Mule deer, Elk, Black Bear, Caribou, Buffalo & many Exotics with these heads. I recently released a video on Exotic & hog Bowhunting & of all the animals I have ever Bowhunted have come to believe the Wild Hog is by far the toughest. These heads have done an excellent job for me BUT, shot placement is always the most important. Good Luck in whatever you choose.
