RE: fixed blade broadheads in a crossbow?
There's no question that the design of the slick trick would be more uniform than the design of the muzzy.
BUT
There also no question of the effectiveness of the Muzzy. Not many broadhead makers have been around as long as they have. AND they probably account for more deer than any other two makers combined (no facts to back it up, just my thoughts).
Are they the best designed, most tech advanced NO WAY! Are they deadly affective.. ABSOLUTELY! If you want a good head for a better price then muzzy will be tough to beat. Are there better heads? Without a doubt! But not for $20 a pack!
That being said, i don't use them. I did kill my first deer with one, but have move on to other heads.
