My only real reccomendation would be to get broadheads that fly like your field point so you dont have to resite your bow in....so that would mean either expandables or smaller fixed blades, not the big jumbo elk cutters.
This!!!
And if you haven't shot your broadheads to match your field points, then you owe it to the animal to do so!!!
Like stated above, any broadhead will work. It's where you place it that matters.
I shoot Muzzy's MX3 because they fly like my field tips, they are tough and sharp, and I can get replacement blades for them.
But please, don't wait to find out how they fly on a animal.
