i've been on moment for 3 years now. can't really say much about their park skis though.
i would go with the jibs since they're a little wider and would handle a little better out of the park.
but if you want something even wider (which would be better for out-of-park, but maybe not so much in-park skiing), i would go with the Tahoe. I loved them. but then again, i really have some weird moment obsession.
haha, that's all i got.
