The more I see #38 the more I like it. I would like to see some other variations off the concept of #38 as opposed to #52 if you are willing. The only thing I can think to say that would give you some direction is to make it a little "softer" somehow. The font lends itself to a techno feel and I like it, but I would be interested to see if you could soften it up a little bit or at least make it a little younger.
