I shot the Libertys this past year and I was disappointed. The blades aren't the problem but the aluminum casing just doesn't hold up. I'm going to try the Wac-em broadhead of the Magnus. I like the cut on impact type blade.
Last year I tested these and the Wac'em and I loved them both. The wife ended up with the 85 grain bh on her setup and I had the 100 grain Wac'em. I would recommend them to anyone. I found no difference with either head vs field points.
