Range. I just like the image of the ranger. Plus, I'm fairly skilled at archery, throwing weapons and crossbowmanship (heh?) in real life, so it's a natural transition.
Thieving - Because it owns. My favorite skill. Attack - Ninja skillz? Defenders? Hitpoints - A byproduct of combat, I guess. Cooking - Another fun skill. Agility - Again, Ninja skillz? Another favorite.
