Hankook Z211 vs Kumho Victoracer

Looking for some informed opinion about these two tires for road racing. We're currently running the Kumho Victoracer V700 (195/55/14) on a Fiat 124 in SVRA events. The vintage orgs don't let you run any of the "slick" DOT tires so we have fewer choices. Am relatively happy with the Kumhos- they have decent grip and wear pretty well- except that the seem to fade a bit after a few hard laps. Looking at the Hankook Z211 if the right compound is available.
Any experience opinions for comparison between the two?

Just found out that Frisby had just one tire left so this thread is moot unless anybody has another suggestion for that size. The Toyo RA1 looks good also but is 10% heavier than the Kumho, which can't be good.
