OK,

The only race course I can comment on is the Richmond one since I have not ridden anywhere else. Having said that, I think Charlottesville and Alabama are both similar to Richmond so you might use the same tire for nearly all of those races under similar conditions.

I would say that if it is dry weather, the Crossmark would be a faster rolling tire than the Advantage so I would choose that one in dry conditions, or your Larson. However, if it is wet, the Maxxis Advantage might be a good choice for a front tire. If it is a total mess, like Milwaukee, the 1.8 Medusa is a good choice in slippery mud.

There is a difference in rubber between the Crossmark UST and the non-ust version... the non UST is much softer and better in slightly slick conditions. Using Stans will make that tire a good choice in wet conditions.

Hope that helps!
