I've learned from several H16 national champions that in very light air, flatter is better, so the wind stays attached to the leeward side, aft of the pocket. This also dictates your batten tension (looser is better, which seems counterintuitive to newbies, who usually first learn that bigger pockets equal more power). As mentioned above, tighten the other controls until you get max power without hooking and screwing up the flow in other ways.

Flattest H16 main I ever saw was Enrique at the NAs in RI in 2006, on one of the light days. I never knew you could get one that flat. He had a huge pointing advantage over the rest of the fleet.

Hope this helps.
