Keep it flat!
The links below this page have much advice, mainly from Mike Lyons, on how best to sail the boat. These are extracted from the 'Blaze Forum'
Regarding sailing style - get to know the boat whatever you do; it will take a few sails to do this. Then start experimenting with kicker adjustment. If over powered then apply more and vice versa. Use mainsheet tension as the main way of powering up the sail. it will close the leach without pushing the mast forward and therefore give you more drive and pointing ability.
