I have the fiberglass platform and I hate it. It splashes water everywhere. I wish I could have gotton a tube platform. But at any rate it is better with any platform.
The tube is a better look than I would have expected. We have the fiberglass platform and it really helps keep the dB's down when you are docking. My issues have been around the lid for the stairs.
If I could get the stair lid secure, I would have less vibrating. That is one of the projects between now and the heart of the season. Plus, we have more room to shower off. All and all, I am pleased with it.
