The topsheet on last years WWW had a PTEX topsheet, and a ghosted smiley face in the middle there, so with the lighting on that picture, it doesn't look like a "normal" topsheet.
Ahh gotcha. Gave me an idea though. Wonder if Grip Tape would actually work instead of a stomp pad and provide grip all day? Unless it freezes over? Might not be a bad idea and kinda like the look.
