[Fot] abradable coatings

I weighed the Wisecos and compared them to some Malhe cast pistons I had.
I'm doing this off memot but I think I weighed them with wrist pins but
without rings.  The Wisecos were about a US pound and the cast Mahles 1.3
pounds. The wrist pins on the cast ones are heavier than the ones that came
with the Wiseco's.  How much lighter are the custom Malhe's?
