Its hat they use in there snowboards and it is what is in the scratch fs its a hybrid between ood and foam. The scratches come from the snowboard factory.
I just had this discussion with some people and the rep for rossi.
Second i have the 03 04 rossi brochure that shops get in my hand. 03/04 Dealer Portfolio
Heres what it says
There are 4 Models 2 use THC and 2 use WOOD

2)Scratch FS THC core Rubber topsheet Freestyle/park ski.
3)Scratch Wood Core Regular topsheet ('its got the look and attitude of its big brother. An excellent value.') Freestyle/park ski econo price, Same dimentions as scratch fs 110/80/103 Size 168,174,180.
