you wont really get fair answers on burton gear here, the only thing i've heard anyone like here from burton are cartels. not because the gear is bad, but because its the whole "i'm to core to like burton" attitude. not to say everyone who doesnt like burton is like that, just most are.
i demoed the 07/08 se7en and really liked it for what it was. i was looking for a jib board at the time so i only had it on two full runs at copper, top to bottom
i thought it did really well on grooms and descent on steeper rougher terrain. its not the fastest edge to edge i've ridden though. it has really good pop for ollies and a confident feel.
if you want something softer i really really liked the Jeremy Jones, only thing is...its really not as good without est bindings, so board binding will be at least $700..
That thing I do to escape the world and have fun with my friends
