The 300 series or "Medium Resilient" is the best stuff. The 200 is like the stuff that comes stock on the H20 and is too slick. The 400 is like sandpaper and terrible. I've been using the 300 for years and I love the stuff. The 2 inch strips are not quite as wide as you might like but is just enough. I wrap mine about a 1/2" over the rail and it has some serious stick so that it doesn't come up. Round the corners when you cut it so that it will stay down better.

The only problem is that it only comes in 50ft lengths so you end up needing to split it with a freind.
