Familiarity: I've put it through the wringer
I have thousands of miles on this as a rear tire (Nobby Nic front). I had just over 2,000 miles on one, and 1,800 miles on another -- no patches. I punctured another directly through the center of the tread after 20, but that's not specific to this tire, given other experiences. Given the light weight nature of these tires, I've been extremely happy with that track record.
Prior to using the Rocket Ron tread pattern, I used the Racing Ralph -- I found that the Rocket Ron offered a more pronounced tread with more predictable traction points, yet not too much knob which would prevent intentionally sliding a corner at speed. As Goldilocks said,
