They seem to fly a bit straighter, and produce a larger cutting diameter. Do they fail often? Penetration seems to be no different, arrows pass clear through with no problem.
Angular hits can be problematical with the mechanicals, I've tracked one down that had this happen, it was an angular hit and was like the arrow hit and opened on arm and then just died after a couple of inches of penetration. Saw another one that hit shoulder blade on a deer and the blades never made it through the shoulder blade. When we picked up the arrow, it was obvious the arrow his solid and all three blades opened, but never made it in more than just past the broad head shaft. We lost that deer. It was shot from a Mathews at 280 FPS with a 395 gr arrow, plenty of energy, but the mechanical seemed to just suck up the energy when it hit the shoulder.

I've seen the damage from them when they work, and they are definitely devastating. I've just never seen a Muzzy or NAP Thunderhead fail when it should have been effective. I just can't say that about the mechanical, and had multiple Muzzies through the front shoulders of a whitetail.

A well spin tuned muzzy or NAP is going to fly just as straight as the mechanicals as long as you are not pushing them over aprox 280 fps. I've seen them get wind plane off of the blades at faster velocities. The NAPs seem to handle the 280+ velocities better than the Mozzy 3 blade heads. The 4 blade heads are better at the higher velocities out of the Muzzys.

Spin tuning carbons is a serious PITA, but I learned to do a dozen at a time and the ones that I can't get to tune before the epoxy hardens become practice arrows. The rest stay set up for hunting. I make my own arrows, and the better the production process, the easier and better they tune.

Yep, now I'm rambling...
