Fantastic. I like
#250 as it is. The one final change I would request regarding #251 is again to make the graphic just a fraction smaller in comparision to the rest of the logo.... say 10% smaller than it is now.
Then, if you would be kind enough to do both logos as a one-colour logo like you did in #214, but with white logo on a light blue background (i.e., the same light blue as per the "pro" in the colour logo), then I would be happy to end the competition there.
Cheers, Steven.
