The correct term for the board shape you are looking for is a "Pig". The actual screen used decks were not actual Valterra Decks (as their lack of concave and almost flat tail made the stunt work impossible). Since stunt double Bob Schmelzer was sponsored by Madrid at the time (and Madrid actually manufactured Valterra boards as a price point skateboard for sale in toy/department stores) a professional quality Madrid deck was used and screened using the graphics templates for the Valterra deck. The decks used were the same type that were marketed and sold by madrid at the time as the "Madrid Explosion". It is no coincidence that a sticker featuring the explosion graphic (which is somewhat similar to that of the splatter) is prominently affixed to the bottom of the screen used Valterra along with other Madrid stickers. The Explosion decks were reissued a few years back and can still be found at various online skateboard retailers. I hope this helps.
