For HPDE's I don't really notice any issues with heat cycling. The tires do get harder as they age but it is something that you work around. Once I put a new set on you can tell the difference in fresh tires but the old ones work fine if you're not collecting trophies or trying for lap times.
It takes me 10 or so days to get them to the "slick" stage.
The nice thing about the Nitto's is they aren't directional. They have an inside and an outside, so you can rotate the tires to any wheel position.
A friend of mine runs Hoosiers on his SVT and he is much faster through the corners than I am, but he spends twice the money for the tires and gets half the number of events.
