Default Mahle pistons

Just wondering if anyone has any experience with Mahle pistons on the street that have the 1mm 1mm 2mm ring pack. Any blow by issues after lots of miles?

Great pistons, but unless your reaching for every last bit of friction reduction and weight loss as it relates to ring flutter I don’t see a need for anything less then 1 and 2 being 1/16” for a motor needing to go the long haul.
