Azenis are good tires, but unless you really don't have any competition in GS, you lose. My estimate of the difference on a 40 sec. course is ¾ to 1 sec. That much would generally move me from first to 4th or 5th in my region (assuming Carpenter doesn't show up -- If he does, he beats me a couple of seconds -- half sec. for the car and the rest is driver).
That said you can still have a lot of fun with Azenis and they are a lot better than the run-flats.
