Moly rings and nitrous

I'm also looking at these;

These are 1/16 rings so I'd have to switch pistons but the top ring is ductile iron as opposed to iron and plasma moly coated instead of just moly coated. Plus the pistons and pins I'd be switching to weigh in at 800ish grams as opposed to the 600ish gram ones I have now. Think its worth the switch? Better rings with more rotating weight.
