Tactilize A/B testing. Left or right ?

My dearest dribbblers,

Céline Andrieu and yours truly, are in the process of redesigning the Tactilize ipad app UI.

We're having a situation.

The fact is, we can't choose between the light bar on dark BG (big here in golrious High Resolution ) or the dark bar on light BG (big here in glorious High Resolution ).

So I'm asking for your contribution here. Left ? Right ?

Discuss.
