sorry man, but thats no wear near tailpress, you could stand strait up while slideing like that and have good balance, the edge of the bux is directly underfoot, so it would be just like a regular rail. If you gona claim tailpress it needs to be atleast under your back binding, and thats still iffy.
skierkid...... ots fags like you that give park skiing a bad name. give the kid the props hes worth, cuz thats pretty nasty not to mention in an indoor arena.
