gott jump in for a second - i'm 6'4", 195lbs and downright love love love my RT 168. this board took me up a level in riding. i borrowed one last season as a rockboard on the first day on the hill and never gave it back - bought the demo from vin that afternoon getting back to out of bounds.
i have ridden that board in 5" of fresh powder, bumps, crowds, you name it. it's just like cranking a big skateboard - turns on a dime, snappy tail to pop you out of turns.
i also ride a coiler 169AMX which i reallly like, but i miss the edge hold that the RT168 gives me.
i rode an oxygen proton 185 yesterday for the first time and offered to buy that one on the spot as well...damn, so many fun boards out there to ride!
get the RT...ride it, have fun.
cheers!
