that was fast!
I don't like
#163 - not exactly sure why but I think it's related to the ab being so small in the box.
I think any theme with the B laying down is out. (there were two founding partners of the company back in '96, and the "B" passed away in 2003 - something which this logo theme is strongly reminding me of).
#161 is better. I don't like the size differential between the A & B. The size, style, and spacing of the text portion of
#161 is very good.
