I have used the standard 100 grain heads for going on almost 10 years now and they flat out work on elk. They fly straight and are reusable, the blades resharpen easily, and they put game down fast.
My bull this year only took 7 of my steps from shot to where he fell and was down in less than 10 seconds. I am a believer in the 4 blade hole. That bull was the 4th elk with that specific broadhead. It blew right through the bull broadside and landed about 15 yards past where I shot him. The blades were dinged up a bit from rocks but it spun perfectly true!
I highly recommend Tricks!
