I think I’d be Offler due to my temper. But I’m a little naive, like Twoflowers offset by a bit of Vimes’s cynicism. I also have Rincewinds memory for important things, and Dorfls feet of clay (not to mention his brethren, Klutz, Shmatteh, Meshuggah and Aghammarad).
But I think out of all of them I would have to go with Not-As-Big-As-Big-Jock-But-Bigger-Than-Medium-Jock Jock.
