As a fairly new guy at this Im still trying to sort out the must-do's from the should-do's from the the don't bothers. Anyway, I bought MA props (glass filled nylon or whatever, you know, the black ones) to use on my trainer with a TT .46 Pro, sanded the "jagged" edges off and Im wondering how to balance them. Can I use a door nail or somthing or should I hike back to the L.H.S for a gadget? Should I even worry about it if there seems to be no significant vibration? Thanks. Randy
