I love the idea of a watercolor surface that accepts paint the same as paper but doesn't require blocking. It would be wonderful for plein aire although, as I found with the pasteboard, the larger sizes get very heavy. I wish it was on gatorboard instead. I seemed to fight the surface a bit but it was the first one so I think it's too early to vote. This would be nice for framing and at 6"x6" the size paints up quickly.
