The Winning Sports are rare as fook. It was me that bought the one of yahoo japan auctions last week. Only 2 known examples so far that can be verified in the UK. Pandemonium on UKSO has one on his GT and mine will have soon. I don't know anyone else who has one on the forums (there may well be)
Yes has visable matting underneath, but thats underneath. Whos gonna look at that?
Plus its different compared to TOMs and Livesports.
