i like 21/27 on the street
22/28 is unnecessary and to much street pounding if you eliminate the rubber t-bar bushings.. besides 22/28 in such a case will seem like cabin rattles are just 100 miles away

then figure if you get very good expensive street tires the side walls are stiffer than the cheaper ones

21/27, no rubber suspension bushings, good Bilsteins, and expensive tires make a trick 911 street car that can safely cruse 100 mph all day effortlessly on the back roads of Nevada

all above in my opinion
