I can't speak on behalf of the others. But, I will tell I have shot the 3-blade but had a hard time tuning them. I went to the 4-blade 100gr. and its like shooting a field point. I have converted several of my friends to switch from expandable to the Muzzy 4-Blade. I shot an 5x6 Elk in Sept. from 37yrds with it.

Thanks and good hunting!!!!
