Yes, I have seen that combo as a pic somewhere on the net. I thought it looked great! I too have a Kona Blue, and have been toying with different options. The silver striping on a Kona blue looks fantastic. Here is a Roush one that, if it were me, I wouldn't have all of it on there, but some of it would look great.
