The Rome Agent is something you also take a look at. It is a great park board that also handles the entire mountain well. Pair that up with a set of Rome 390`s and you are solid gold. For your weight and desire to do more park, I would go with a 152 unless you expect to bulk up in the next couple of years, then step up to the 154.
Well it was either that or the Nitro Team Art attack and I'm not positive which one I want to get, but I was leaning towards the Nitro just cause I've ridden one before.
