I didn't want to go into too many details, but yes, I actually have RS11 front now. I mounted it for the track day and will replace it with the S22 from the set I bought when it is worn out, this way hopefully reaching end of life of two fronts and one rear around the same time. But I never had any problems with S22 for everyday riding. Haven't tried Q4 yet. (I live in Seattle, with some almost vertical streets, often wet)S22's are great.
Rs10's are better in my opinion.
