Yeah the CSC5 indeed inspires confidence. To me it's also still pretty comfortable but my sidewall is still around 11cm thick. Anyway my next tire change I want to try different ones, maybe the Fleva or V12E2, or PS4 if I got the budget, but that will still be another 1-2 yrs from now. So in the mean time should have more and more reviews on these tires, maybe will come upgraded versions again too.
