Ya the Nug sounds like a good choice for what you're looking for. It's a twin, which is good if you want to learn switch. It's got medium range flex and is a rocker so it will be a fun, easy to maneuver board, but not the best at high speeds and steep runs. At your size, I'd recommend getting a board in the low to mid 150ish range. A little longer than park riding, but you want to keep it fairly short to maneuver through trees easier if you're looking to keep doing that sort of thing.
