Several chiming in on the blue reynolds ones.... Ive ridden reynolds and neuvation tubulars on yellow swiss stops, corks, and koolstop carbon compounds. Nothing spectacular on them.... dont brake as well as alloys when wet. Put on some of the blue ones on my new reynolds, and they are downright terrible wet. Put em on for a wet race and was giving up my wheel all day as I didnt feel comfortable with my stopping power back to something/anything else, even though reynolds wants the blue or else voided warranty.
