I would guess the left handed adapter plays exactly opposite of the right. 11.5 = 8.5, 11=9, etc. I would also guess the draw settings would play open. This is the only sense I can make out of him using the left handed adapter.
According to the Golfwrx review on the regular head Bio Cell, the face goes from .5 * open at the lowest setting (8*) up to .75* closed at the 12* setting. That would make the 10.5 setting to be almost square (about 1/8th degree~ closed). If Ricky is playing it at 8.5, it would be slightly open anyway.
does anyone know if there are two versions of the head like the amp cell pro? Silver piece on the back more neutral/open head, sliver piece on the toe and back more closed.
