I don't have a solid opinion on all the boards on your list, but I'll give you what I got.
The Raptor is an awesome board if you're looking for something to point straight and go mach 10. IMO it isn't the most playful board because it is really stiff. Might not quite fit your riding style.
The Hovercraft would certainly be super slashy fun and great in the trees. Might be a bit slow edge to edge with how wide it is though.
Yeah the Birdman is not for you.
I've been intrigued by the Dirty Pillow too, but I'm turned off by the full banana rocker. Seems more like a park board that can handle pow. If you enjoy your GBoH for freestyle pow, you probably shouldn't consider the Dirty Pillow.
I definitely support the Salomon Powder Snake, but would even more support the Sick Stick if you can afford it. Definitely not a twin though like they say, it's a pin tail. I own the Sick Stick and it's probably my fav board I've ever ridden. Great float, super fun and slashy. Great pop, and the 163 I ride is super maneuverable in the trees, I imagine the 160 would just kill it. The Pow Snake is the same shape, but a bit stiffer. You lose the snap & pop of the bamboo, but the board will probably hold up a lot better (the SS is a bit fragile it seems, the bamboo top sheet chips easily).
