The prob with the wider LE was IMOHO with the prop wash that in certain situation (yaw) prevented one slat to fully open. Having yaw angle is fairly comune during a DF unless you stay focused on your slip angle.

This is not correct, when the aircraft is pulling tight turns the g load on the slats makes them snap open, they are designed only to open gently at slow speeds for landing and take off.
