I've been riding them for long enough I've forgotten what alloy braking is like.
Whatever adjustments I needed to make is bedded in my head, so I'm never thinking or conscious of "carbon braking" when riding. Except on extended descent when i do try to pulse it rather than keep the pressure constant.
And obviously in the wet it's pretty atrocious.
Otherwise, in 95% of riding condition, it's all gravy. Wouldn't hesitate to buy more carbon wheels
