A differnt Tyre question

[steve-V8s]

I currently have a set Yokohama AO32rs in the original sizes 245/45/16, 205/55/15 the time is approaching when they will need replacing. The 32r is now largely replaced with the 48r and also in the frame are the R888 and the Dunlop equivalent.

Any comments on which is the stickiest and what sizes you have found, not really worried about wear rates or wet performance just want lots of dry grip. Prodded a set of R888 on a 911 the other day and they felt very soft, I think however they are available in various compounds.
