Schwalbe Pro One Addix, 28mm: I ran these for all of 2020. Great tire: supple, fast, good grip and feedback, decent mileage, no premature death. These felt pretty nice on the Assaults, but even better when I went to the wider Zipp 303S, particularly in terms of throwing them in to a corner. In terms of performance, these are currently my overall favorite.
These mounted and seated very easily on both the Reynold's and the Zipps. In fact, they mounted/seated too easily on the Zipps, and that's the cause of the only negative that I have against them - they don't stay bead-locked on the 303S when deflated, which makes sealant maintenance a bit of a pain (and gives me a small bit of worry about the prospect of a big puncture at speed). I'll probably come back to them at some point, and if I do, I'll try double-wrapping the rim tape to see if that tightens them up enough to stay locked.
