I have my pinball machine on hardwood style vinyl, and while its supposed to be scratch proof, I don't exactly want to test that out with some serious tilting. So currently I have the pin on rubber pads, however they grip so well that it seems to be hindering my ability to tilt effectively. Does anyone know a good floor protector that isn't just rubber? I've thought about trying the felt pads, but I think those will just let it slide around too much. what do you all use? TIA!
