#19 - let's try putting the "swoosh" behind the lettering; make the "A" the same height as the "IB"; use colors other than blue and green, such as maroon, gray, dark blue etc.; let's try making the swoosh semi-transparent in front of the IBA
#16 - we'd like to try another image that matches the font of the letters - a little more design to it - we like the font;
#17 - we don't like the "A"; try replacing the "iBA" in #17 with the "IBA" from #16.
