I appreciate the attempt at the stylized RB, but it's not working for me. A s a matter of pure design, however, it is nice stuff. The one that works best, is #39, but RR does not make sense.
A s I said in the general comments, initials have an uphill battle The only stylized version I've gone for is something like #11 because it is not very obvious.
I need to run to work, and will give some more feedback later. #85 still my fav. #95 too literal and the other graphics are getting farther away from the lens idea.
Like script, but not these particular fonts. I'll post more later. Gotta go.
