After nearly two decades of messing around with all kinds of broadheads, mostly cheaper, but some not, I finally found one that shoots consistent and stays sharp:

Montec g5 one-piece stainless steel

The blades don't move cause they can't move. One broadhead shoots exactly like another. No tuning. Just shoot and be confident. They shoot like field points. I have 125 gr that I used on my crossbow. Then, I put them on my regular arrows and they shot consistent with a Mission Craze bow. The best part, however, is that you can resharpen these broadheads even if you are the 2nd worst sharpener in the world (I am the worst). You simply sharpen two edges at a time on a flat diamond stone - the angle is always perfect.

There are other similar one-piece broadheads. I would bet that the NAP Hellrazor would perform just as well and offer the same benefits.

I will never go back to moveable blades.
