heh, i had a friend [since retired for frisbee golf] who usedta fakie bigspin tail every yr on video. sometimes they'd go to 5-0 but between us, those were accidental.
he had fs 180 nosegrinds too, that frickin trick always goes to noseslide to fakie for me. i can do really short fs chink chinks on the last 12-18 inches of a ledge but not really sit on the switch 5-0. there's a shitty park ledge that goes up, flat and down that i've 180 nosegrinded the short down slope but it's sort of cheating cause my board is prolly level, the incline is doing the work.
