I would go with the Faux Teak Sea Dek. It's does not get any warmer than carpet on a hot summer day. It has a nice feel to it and is not hard at all. The biggest benefit over carpet is that it does not absorb water. It's a closed cell EVA material. I'm looking forward to being able to spray down the interior when washing and not having to remove the carpet.
Also, I love the look of it and the logo carpet is hideous in my opinion. Way too busy of a design.
Here are a couple photos of my new 210. The Sea Dek isn't a factory option yet for the 210 so I had to get it directly from Sea Dek.
