We still like #77 the best, can you please submit #77 with a deeper red.
Also we like the black touches on the R and K but why is the K split, is that on purpose because it looks better? Lastly did you modify the A in this font to have that look?
Since this logo is truly a great design, unless you feel absolutely inspired to do something completely different, can you please try different things with the font, just minor tweaks to see if it can be improved. Don't forget that we love the R but please consider playing withe font a little and see if you can do something better with the A and K.
