I love the Nitrons. They fly like darts, they're made from steel, you can replace the blades if you have to, and they're sharp as HECK. I've killed two deer this year with them. The doe was quartered away, I double lunged her and blew through her offside shoulder- the broadhead still looked new.
They're basically NAP's version of Slick Tricks.
They look small, but they're only like 1/16" of an inch less than most broadheads- they just look smaller because they're short.
