I ran a set of K2 Formulas on mine once last season and didn't think it was a good match as the Formula is more of a budget binding. I ended up running the Now IPO with medium and/or firm bushings all the other dozen times. It was a great combo. My buddy also tried the board out with his Forum Shakas and really liked that combo as well since the board has a nice flex in the waist with the stiffer tip/tail.
