A lot of people don't think about piston weight and the effect it has. Here's some examples of the 800's out there.
800 e tec , cat 800 and axys 800.
E tec 800
Axys 800
Cat 800.
Now, the poo and cat are 85mm vs the Doo at 82mm. The Doo piston is way to heavy in my opinion and it's smaller. Should be 50 grams lighter . The Polaris could be 30-40 grams lighter. The cat is OK were it's at.
The weight of the pistons has a lot to do with reliability, not just the tolerances. It's good to have a tighter (0.00525") tolerance when new for sure.
I'm just pointing this out
