I have a Hybrid with a slide but I didn't replace the vinyl, I added to it. I installed a 5/8" soft floor over the vinyl one for my dog to make it softer, quieter and warmer for my feet at night when I'm barefoot. I have no problem with the extra 5/8" of height added to the floor. The slide goes over it and never touches it going in or out. It's been installed for a year now and no damage from the slide but this is not a floor for high traffic 24/7 but great for the 3 of us and still looks new.
