KH Discs vs 73+ Discs

I voted KH, cuz they re awesome.
However, because of his situation, I would kinda lean towards the single piston set-up.
Naw. I love my KH/Dot5/braided lines set-up. Its been working 100% for 15 years and 125,000 miles with zero maintenance. ZERO. You wont get that with the other.
