What category are you guys racing? That makes a big difference in what kind of tactics you can employ.
Also, what kind of strength has your team shown in the past in that category? If you are one of the stronger teams, you'll more easily be able to go ahead with your offensive moves, but if you are one of the pack-filling teams, you will have to rely more on defensive tactics.
Let me know and I'll see if I can help you with my infinite cat1 wisdom :-)
