I started out with muzzy, 4 years ago. They are durable but some of my arrows I put them on don't fly as straight as I would like them to. I Switched to Thunderheadsfor a year andlast year switch toLiberty heads by American broadheads,Inc and I love the way they shoot. I like the way they fly, straight and true, just like field pointsand the cut on impact is great.MUZZY IS BAD TO THE BONE BUT LIBERTYHEADS FLIES STRAIGHT AND RIGHT THROUGH.
