2. I was probably pointing a little high trying to keep the boat down which is a little slow...
A possible solution (dependents on the cut of your mainsail)
Crank on the downhaul hard (after the mainsheet is already tight) and let out some mainsheet. The top with both flatten and open up and start to stream. You have to find the right setting and may point a little lower then the other boats but have a hell of a VMG due to high speeds.
