Many years ago I played around with the take off point for the mainsheet. At one stage back in the 80s I even had it so it was adjustable on the water.

Moving it further aft of the traveller helps induce mast rotation in light air but makes good controllable leach tension a little more difficult. This is especially so in heavy air because a component of the force applied by the mainsheet is trying to push the mast forward. To make things worse in heavy air the mast has the rotation reduced which increases distance the take off point is behind the traveller and therefore the component of force pushing on the mast and as the distance from the sail to the traveller shortens the force on the mast increase further because of the changing angle of the mainsheet.

At one stage I made up a shock cord setup that automatically rotated the mast once the rotation limiter was eased and this seemed to work quite well and required no intervention at all once the boat was rigged.
That way I could rig the boat with the take off point where I needed it for trimming the main because the shock cord took care of inducing rotation.

While is is fun to play around. It is faster to just go sailing.
