dont really know a whole lot about the dark series or trice, but the TRS i have is really good for freeriding. it is stiffer than both of the boards you are looking at, but im not sure if it comes in c2.
im pretty sure the t rice is stiffer than the trs but i could be wrong
Softest to stiffest is TRS, T. Rice, Dark Series. I think you may need the wide for your foot size, but this isn't my area of expertise. Hopefully others will chime in.
