I like the Surly Disc Trucker fork on my Traitor Ruben. It's got all the mounting points for fenders and a front rack. Plus it fits a 2.1-2.2" tire, which is definitely awesome in the winter.
I wouldn't worry too much about trying to save weight with a carbon front fork. How much are you really going to save over a steel fork? half a pound, maybe? That kind of savings really isn't gonna do much for a commuting/exploration bike.
