159 and 160 are very cool. 159 could be too "digital" or "pixelated" (I'm looking for the right word), although I still really like it. Might even look good if the white and color were reversed where the "m"s were "invisible". 160
Could 160 duplicate the "m" like 159 does?
Thanks for these really good entries. (77 should work for some law firm with a B that does a lot of criminal/courtroom work - it is a very nice design even if not for us.)
