Planning on rebuilding my wheels and I can't decide whether to get the Duallies or the Blunt 35's. Currently on the older Stan's Arches (19mm internal width). Bike will be a rigid Karate Monkey SS. for people that have ridden both is the price/extra weight of Duallies worth the extra 9mm of width (internal) or is moving from 19mm to 30mm internal on the blunt's plenty. I do not plan on trying to squeeze 3.0 tires on them. Probably 2.4 trail and mountain kings from Conti or maybe some 2.4 Maxxis Ardents or a 2.35 Maxxis Icon.
