Whatever u want or will work for you and your riding style. Just be sure bindings are wide enough for your wide boot.
I'm using L/XL Forces with my 8.5US Dialogue Wide because of width.
For SL I suggest Rome 390 boss for more park, Rome Targa for more allmountain/freeride also check K2/Ride lineup (Formula,Indy,Alpha or Delta). Some people here really like Flux bindings, so take a look at them.
