Not sure who else does that.

I would not use a hypereutectic piston in anything. TRW forging is OK for a cruiser.

Based on the options in the poll, I would bet there is a budget parameter here. Autotech has a good reputation for building what you need, but any custom piston isn’t necessarily going to be budget friendly.
