Some bendy/floppy all green beastie that was the same material all the way through. No slick, no deck. Thought i had invented the wheel when i screwed a couple of fins in that were some almost fluoro orange colour. Would have made a massive difference, as i don't reckon it coulda held a rail in the scoop too well, haha. Still remember my first barrel in the sucker on my first ride (before the fins
) , was hooked from there, that magic see-through curtain. Late 70's/early 80's ruled for odd boog craft.
