I'm really lovin the Montec G-5's. Milled from a solid peice of steel, no parts at all. This head groups really well for me as well. The penetration is incredible, I put one through two 4" wide broadhead butts, 4 spaced layers of hanging 1/2" felt and buried it up to the insert in a fir fence.....no damage whatsoever. I shot a smallish muley with one this year, before the deer took 2 steps there was a patch of blood the size of a volleyball on his side, the deer went about 45 yds. The shot was 52yds and I recovered the arrow a full twenty yards past the point of impact. Sharpened it up and its back in my quiver ready to go. I can't say enough good about these broadheads, I'll be shooting them as long as they keep making them!!
