Wossner or Pro-X Seadoo 720 Pistons which better ?

[MEJETSKI2000]

Rebuilding Challenger motor which will need 1.0 mm OS pistons. Which piston would have better longevity, Wossner forged or Pro-X cast ?

I prefer the Pro/X and they are actually OEM on the Japanese skis.

I hear wosner are good but know nothing about them.

On my skis if I can’t use OEM I use pro-X.

Also forged pistons take a different setup clearance and need a longer warm up before full throttle runs.
