Ah yes. Debating left or right. :p
I think expert consensus is that the right leg is the spinning leg - the left is the mashing leg... I'll have to take a closer look next time I see you but I am guessing your left leg is HUGE.
I would argue it is the reverse
I think my right leg is the mashing leg since my right leg is slightly bigger than my huge left leg. And I'm working on it to switch. So that means I'm going to have spinning right leg...
So it sounds like you really ARE working on your spinning leg (singular). Interesting.
My true intention is to work on my both legS!
