What is a better piston WMS piston or namura

[trickedcarbine]

Has anyone actually had both WSM and wiseco pistons in there hand at the same time to compare? I have.

And I'm not running wiseco in my bike. But I'm talking forged.

Regardless cast or forged, both are fine as long as you have the proper clearances.

I like Weisco for most stuff, but my big bore motor got WSM. Priced well and pretty on par with quality.
