The problem with light wind sailing is it is very easy to hook the mainsail by over sheeting. My preference was to move the traveller to the centre of the beam (rather than the more usual 100mm from centre) and then have the mainsheet a little slacker so that there I a small amount of twist in the mainsail. I would also have less downhaul tension to get a slightly fuller mainsail. I would also sail a little free-er to maintain momentum - this is especially important if not sailing on flat water. Move your body leeward to prevent the mast leaning towards the wind.
Having said all that, the best light wind sailor in the fleet is probably Stuart Snell and I notice that he sails with a flatter mainsail and points higher than me in light winds. He seems to be able to maintain momentum when pointing high and makes gains in the lifts by being on the very edge of the wind, where the lifts are more apparent. I put this down to concentration.

PS May be Stuart will make a post and share the secret.
