The letters in the lettermark have to legible at first sight. That is what is attractive about #23, #27 and #44. I would also like everyone to look at the font used in the following contest as it looks very professional. A lot of the fonts being used are way to big and bulky if that makes any sense.

I think we are leaning more towards having the lettermark on the left with Ray Martin Company and Mechanical Contractors to the right of the lettermark. "Of Omaha" is purely optional from a logo perspective as it is there for legal reasons only.
