pipe cleaners are pretty fun, but they're not very stiff. with your weight, i'd go with the wall, as they are substantially stiffer. walls are snappy, quick, durable as hell, and generally a rock solid ski. if you do spend as much time outside the park as you say you do, why not check out the bridge instead of the wall? still really fun in the park but they actually kick ass everywhere else.
