Depends on where you are on power v drag. Once you have all the power you can use then you are reducing drag, downhaul/ Cunningham on and open that leach45-50% aft is about normal for a mainsail with a headsail in front of it. Moving the draft forwards would open the leech reducing both power and pointing ability. That's not going to help you win a race.
