I do most things right handed, but some few things I do left handed.
In the Norwegian dance "gangar", you tap both feet, first one foot, then the next, kind of like heart rhytm. Right handed people would tap right foot first, but I start with left. Snowboarding I do wrong way too.
I've tried slinging left handed, pretty bad, but figure-8 was easiest, dunno why. I'll practice a little, perhaps I can get better.
