So faster getting flats?
I have no experience with them as they are new. I’m running a pair of Racing Ralph’s/Racing Rays and in my long experience with Schwalbe MTB tires I haven’t noticed a propensity for flats.
I think most Schwalbe’s are fine. I’ve used the Ray / Ralph and have a set of Rocket Ron. Haven’t had any issue with any of those.
The Thunder Burt have had a lot of Reported Flats, and many people won’t use them on chunkier stuff (e.g. - Unbound). I think it’s probably casing, plus less tread than other tires.
The issue with the Rick - only 2.4 and 2.25 where the Burt / Ray / Ralph / Rocket Ron you can get down to 2.1". And if I’m using 2.25, I’m personally still picking the Race King. But, I may look to try the Rick the next time I want a fast rolling 2.4 on my XC Bike. Maybe Leadville This Year?
