the font on number 76 and 74 look too bold and heavy for me. number 76 and 72 are my favoites. i like how number 72 has the gear deigns on each letter, but i with the gear was something more appropriate for this business... maybe try a honeycomb.
the other thing to note about 76 is this all of New York State, not just NY city, so I want to stay away from anything that looks to City centric.
