Usually you delete the second ring, and the oil control is very small, 2mm or smaller if I remember, since JE does have a line of two ring piston rings. I'm not sure if the weight savings is that monumental. I'd be willing to bet you'd save more just doing a lighten combo on any given piston.

The majority of the flat top pistons I make run a 1.112" pin height with a 22mm pin. On the 356, it is a 1.065" pin height, again with a 22mm pin unless they use the rods I make, then I set it up with a 19mm wrist pin - lighter pin, more material around the boss, lighter pin end on the rod. Any weight savings on a 356 translates directly to longer rod bearing life.
