I like all of these, but I've decided to stay away from the black background because I don't think it works so well for business cards which will be my primary use of the logo for the time being. For #60, could you fit the subtitle in there somehow ("Custom Mapping and Geospatial Analysis").
#66 This is a really nice way of combining both globe and compass in one! I really like it! A little too much green though because I will be putting the logo on the custom map products (sort of like an artist's signature). It's very difficult because it needs to be subtle enough not to detract from the map products, but also distinctive enough that it can hold up on it's own on a business card. I know this is a tall order...thanks very much for your efforts to date!
Also, I've been reading through the forums and found an excellent point - that I should see what the logo will look like in grayscale for those times when I would have to put it on maps that are going to be reproduced. Any chance you'd be willing to generate a grayscale one for me?
