Congrats on the Koni Yellows! I have heard great things. I have the FSD/Eibach Pro Kit combo and they are great and comfortable, but the spring rate on the Pro Kit might be a little on the soft side if you like a more aggressive set up. Depends on what you will use them for, but all of them would be a good match for the yellows. I prefere Eibach because I'm not a fan of the H&R rake.
Also, my understanding is that the Pro Kit and the Sportline are the same rate, just different heights.
