I'm running Emulsion 2.0 on the 110. Nothing on the roof. Valving is 40/80. I get some roll on the street, but they are great off-road. With weight on the roof and a bias towards street, I would think 90/110. Good thing for you Clay, is Off Road Warehouse is in your area. Go visit them, tell them your requirements, and have them valve them up.
Report back what you go with and how you like it. I'm curious.
