The Commuting forum tends to like cross, touring and hybrid bikes none of which will meet your urban hucking needs nor do well off-road (though some can go off-road).
For on road you definately want a hard tail and probably a rigid bike. For off-road and hucking you want durability and agressive tires.
Consider a 29er like the Surly Karate Monkey. You could run a fat slick like a Big Apple or other semi-slick for commuting and urban adventures and swap on some knobbies sore off-road play. The big wheels will give you a little smoother ride off-road with a rigid bike but the lack of suspension will be a plus for road riding.
I don't have much experience off-road or with urban obstacles but I commute every day. In my experience you don't want to have to push a suspended bike with soft knobbies on the road everyday. You will have to make the trade-offs that are right for you.
