Just FWIW, turbo cottons are so supple that they roll over anything, rather than pick it up, and IMO were very reliable. Way more so than a Corsa.
Corsa Control’a are now my go to for a reliable, fast, relatively cheap, supple tyre.
GP5000s are fast but they’re so dead to ride compared to Corsa’s and Turbo Cotton’s. That sidewall has zero flex whatsoever.
