Check out the Ofna forums, there is a very very nice setup for "Loose" tracks. I am running it with only differences being shock and diff weights and it is just amazing.

My track is a loose sand but packed in some areas. In the corners it will wear down and you'll be able to see where the more experienced racers and sticking to the inside line.

I'm running Komodo Dragon 2s as well and they are awesome! I've found Medium-Soft to be perfect for grip and long lasting(about 5-6 race weekends?).
