I am sorry - these came in late. I had not seen them when I ended the contest and selected the winner. We had already extended 2 other contests we have running called UNITY and GENUINE. So I thought this one was overdue and I chose to seelect the winner. I REALLY like these and would encourage you to enter the other contests.
I like the simplicity of #191 (would still want a different color or treatment to make the U and I stand out) and like #193 and 189 (worried some will not see the U in the word though and think it says R-BICON)
