not awfully short, I'd normally recommend 157 for you, but decided on 161 for you since you're used to such a long board.
I ride a 148 and I weigh 140lbs. and my board is much softer than the Ape.
and with MTX you won't be slip slidey, MTX keeps you connected to the snow...in a good way.
That thing I do to escape the world and have fun with my friend
