I would say that for your weight it might be a little too big but nothing that will be unmanageable as your skills evolve. You don't need to be blasting black runs on your first season either. Give it some time and a lot of practice. If you feel the need get a shorter board for moguls, freestyle etc. I have a bunch of boards that I just kind of cycle through as I get bored with them. Keeps things interesting.
When the fuck did we get ice cream?
