I read it.
The 615's still have heat problems(not as bad as the 215 but they still need water when hot). I run a set and can tell you while they do not get greasy as fast as the older 215's they do still get greasy.
As for the Kooks I have not driven on them yet so I can not say much about them.
I read the R Compound test more than the ST test what I got from it was basically all the tires are pretty good these (Falken) are a little better but pick your poison based on your driving style/car setup and personal preference.
