RE: buggy tires
+1 on the city blocks. However, if it is a med traction track, consider some panther komodo dragon 2's in soft compound. Don't get the super softs. When I had a an eight these worked great in those conditions. I mounted them on advantage multispoke wheels. It was a light and durable setup. I'm not saying get them, but go to their site and have a look at them and consider them.
