The idea is that the chocks allow you to have as much or as little bend as you want as long as the pin does not bind.
Control about the pin is the key!
To take this bend in light winds further, bend the mast with the spreaders and rig tension, not by the kicker, your pull the leach on the main down too tight.
Look at the leach tell tails, they tell you when the wind is exhausting the sail.
Bent mast, flatter entry to the main and a flatter sail. Loose kicker to open the mainsail leach, mainsail angle and leach tension controled by the mainsheet.
