That's what I was trying to say above. Sometimes, I think faster than I type,
so all the details don't make it to my fingers...
Yes, adding pistons at various angles will help even out the "work" required.
So, 2 large pistions at 180 degrees should be compared to 12 small pistons,
at... well... spread around the circle. (30 degrees?)
Or, you could compair 6 to 1 by NOT spreading the six around.
I think the best bet is to try to compare 2 large to 12 small.
