One spring thing never tried to my knowledge is to have the piston head on bearings so that the spring has nothing to twist on. I know the spring doesn't actually twist but it wants to. Someone who knows springs better than I might correct me, or add something here.
The spring does twist and a simple slip bearing is the best cure. Rotating pistons just mean you have more twisting mass and needle bearings don't work so well under extreme sudden pressure.
Opposing, counterwound springs are ok, but I'm interested to see Nicks finding on this idea.
