I had the Nitto 555 DR's and got about 5k miles out of them with a few passes down the track. I also ran some BFG DR's with 1 pass at the track and got less that 1k out of them so I wouldn't those. Alot of guys have been happy with the MT DR's.
I have been running the Mickey DRs from my house to the track and back only and man do they pick up a lot of crap. They look like I drove them through a gravel pit. I will probably start mounting them at the track after I dig the 85,000 pebbles out of them.
The BFG DRs weren't that bad for this but they also weren't as good of a track tire for me.

It really depends on what kind of mileage you want out of them. If you are looking for something that's going to be used on the street, I'd just pick up another set of Nitto's. The new compound is softer and stickier so you won't get quite as much life out of them, but they still are the best DR if you don't want to be replacing them constantly. Other things like the Toyo Proxes and the M/Ts are nice and sticky, but they don't have the wear life the Nitto's do. No matter what tire you go with, they'll be worlds better than a street tire.
