Polycarbonate plates are weirdly nice and yet also downright crude to use. Their softness is in stark contrast to a brass plate's hard bottom out but the softness of polycarbonate promotes quieter switches like the 62g Sakurios, effectively making the bottom out a pillow as well as dampening the noise as well even further than a regular metal plate.
I'm putting my lubed 62g Sakurios back into Echelon 2 since I didn't like the sound signature of the Creams nor the feel, so the Sakurios with their gorgeous quiet noise floor and velvety-smooth keyswitch feel are coming back.

The Sakurios are a tricky one @Cyberspirit, they're not longer sticky but they're also not as smooth as before. When I was putting them back in and pressing some down to test, I could hear chafing and can only assume that's the lube wearing off. Not sure what happened in the few weeks that they were in a jar.
They're a little too light and hollow to me, but they're still perfectly fine linears that I'd take over something like a Cherry Red.
