Claw grip might be required for endgame-minded puff. I'll let you know in a couple weeks but it seems extremely promising. Makes some theory stuff not just practical but reliable.

I have normal left hand
right hand index on Y, thumb on C stick, middle finger rests between Z and R. I raise my right thumb to press A or B. You could use Z for nair if you wanted.
