I think they make bindings more likely to rip out. I don't know why maybe its because the bindings have more play sitting on a flexible rubber platform. I have seen ALOT rip out. Just make sure you get shorter screws if you dont use them
I don't see how they could do anything considering there's screws running through them. If you could come up with a set of elastic screws, you'd be set.
Hmm I never heard they made it easier to rip out but considering I ripped out two pairs of px-12's a total of 7 times maybe theres something to this. I think I'll mount them next year without the risers
