Honestly I feel Pit fits The Concept better than Sheik anyway.
Or at least, when I play you I feel you're more of a Pit player. I suppose that might have changed, but I'm just throwing that out there.
I can sort of use the default setup on Wii remote, but I'm genuinely terrible at it (it's a bit of a struggle to beat a level 9 using it, and if I want to win an FFA with it I usually camp by doing nothing away from the action or plank). But if I'm playing anything for reals, I use a GCC.
