There's a few subtle differences between the tables/inverts and the unturndowns. Tables have bent knees and the handlebars go on the outside of the other arm. UnTurndowns have straight legs and the handlebars pass under the armpit.
Driftrc,
A table makes the bike go flat sideways
A unturndown is when you pull the bar end towards your chest. It's like a turndown but without the bar turn.
Then you're simply reinforcing what I said. Under the armpit ends up in front of the chest. Over the arm is above the chest and makes the bike go flat due to tucked knees and a bent waist. However, when performing an unturndown, the focus isn't to bring the bar end toward your chest. Its to pass it under the armpit by rotating the wrist over the grip and then turning your chest/body outwards to get more "shoulder buzz."
Oh Hot Dayme!! Thats a sick pod! the lighting gives it kind of a rainforest look with the shadows and then the rays of sun peeking in... so sick! great pod for sure
