Back In Balance - RedmondLogo Design Contest

I love the idea of having the 2 B's one inside the other. I like entry #50 more as it resembles a spine. Can you come up with a couple more ideas making the B's a little bit more obvious.

The B's in #53 are starting to look too much like 6's. Is there anything we can do to tweak it?

Maybe try something simliar with capitol B's instead of small b's?

thanks to your feedback. I will try to upload some modified design

(This comment references Entry #54)

Entry #54 is the right idea but now it looks like it is leaning... kinda makes it look akward. Some other modifications would be appreciated.
