Logo Fonts

In designing my Law firm logo, I am researching different types of fonts. In researching different law firm logos, I have found a lot of clean lines, and capital letters. I have yet to find a logo that has any sort of cursive lettering on it. Most logos convey a sense of professionalism and would not be able to do so if there was a large amount of cursive lettering being shown.
 This logo is one I like because of the clean lines and capital letters.

Another example of a logo that I find conveys professionalism is from Townsend, Lockett, and Milfort, LLC. The use of the grayscale lettering is attractive. The only problem I have with this logo is that there is no comma between the first two names.

I did find one logo of a law firm with cursive lettering. I believe that this logo does not convey as much of a sense of professionalism when compared to the other logos.
