Actually yes. I do. I check them all. So far, none has ever really required any changes to balance them, I just get peace of mind knowing that I've checked them.

Most manufacturers props are pretty much in balance when you get them. APC's in particular are because that's pretty much what I use and none has required balance.. I've shaved one or two just playing with them to see if I can get them perfect, but that's impossible. HOLD ON GUYS..[X(].. I said I use APC's. That does NOT mean that MAS or any other prop requires balance, just that my APC's don't. So, don't get yer panties in a wad over what I said.

I use a magnetic balancer (two large powerful magnets on each side of a steel shaft that has a point on both ends with the prop held in the center). I tap the prop and watch it. It usually will move a bit and stop. Sometimes, it may oscillate back and forth, which is when I tried to shave it trying to make it perfect, but, as I said, that's pretty much a wasted effort. They are fine the way they are.
