Let me know which you decide on. I will have to make the same decision on my 24' pontoon. I would need six sheets of 4'X8' to replace the existing plywood floor. It will be a big project but replacing the floor with aluminum would be a huge weight reduction. The previous owner of my pontoon replaced the carpet just before I bought the boat. He used the carpet I mentioned not to use. I have had the boat less than a year and the carpet needs replacing already.
