Any one running one of these or know someone who is? I think Brad got one for one of his saws. Thinking of trying it out in my 2171 I'm putting together.

I have one of the original Bailey's Wiseco dual thin-ring pistons in a saw I've been running off and on for about six years. Parrisw machined the jug for me back when he was still into saws. It's been a phenomenal runner all this time. I've fell timber with it using 28" to 36" bars. I guess I can pull it apart and see what it looks like internally.
That's the one I'm thinking about trying. The lighter weight might let the crank live longer at 15k+. Oem mahle is $80 or so. I'll weight a meteor and oem when the meteor get here in a day or two.
I saw that they offered an all black piston for a little less. Honestly the price wouldn't be a deal breaker for me if the performance increase was significant or if it was proven to help the bottom end last longer.
