I have been racing on a Renn 650c clincher disc for 3 years. I have owned the wheels that begin with Z. The Renn and a Hed3 combo is the fastest out there, period. Wheels are not art. I could give a rats @#@ what color the stickers are. They have to go fast and hold up as well as be affordable. The new Renn disc is an improvement on what I have so it must be terrific. I just got back from the Evangeline Oak Du. I won 40-44 with a Renn, the overall winner also was on a Renn. There was also a Zipp 909 wheelset up at the front with us. My point, all the wheels are great, my wheelset cost $1000, the Zipps cost $1800 and the disc only comes in a tubular. If you need to spend $800 extra on stickers than you should go for it.
