Conditions dictate tire choice
I'd have preferred Kojaks for our two Speed Pros, but they're not available. The only compromise was Marathons since the LBS said they couldn't get Kojaks. (Yes, they had MuSL with Kojaks on display.)
Tire and bike feedback is very helpful, especially for those without local access to total parts and dedicated dealers. The LBS has a good selection of bikes, but few parts, and minimal on-bike experience for meaningful support.
Are there any others in China with supportive, well-equipped shops?
