Erwin, In my opinion these are all very strong. I really like the idea of creating a strong symbol next to the "JC Flow text” that is identifiable and could eventually stand-alone as the 'JC Flow' brand' is developed. So, I very much like the abstract j - C - f you have developed. Is there a way to make it clearer that the symbol in #58 includes a mic? My first thought when I say #58, was a conference call desk microphone… I am also torn between the class and professionalism of #9 and #10 and the more edgy relaxed feel of #57 and #58. Hope this helps. Thanks again for your efforts. JC
