I'm predominantly right handed though I do sometimes do stuff with my left hand such as chopsticks, typing on phones (because I'm slightly faster if I have to do it one handed).
Next person is surprised this thread is still going.
Nope. It's amazing.
Next person loves ShengShou cubes because of the incredible smoothness and uses at least two as their mains.
I use a Shengshou megaminx, pyraminx, and 6x6 for mains.
