What pistons?

[Sospikey]

Pro-X or WSM? I am leaning towards Pro-x. I am happy with them in in my Superjet this far. I'll refresh my X2 this winter so I am starting to collect the parts needed. What do you guys use?

I like Pro-X. I have only had experience with WSM, Wiseco and Pro-x. Never had any issues with WSM or Pro-x just pro-X are better quality and made in Japan. I use Wisecos only when I have to and run them with lots of clearance.
