Ok, I understand what you're saying but assuming your overall "load" on the motor/gearbox is limited to some maximum, wouldn't you be better off attaching ALL of the springs directly to the launcher so that every bit of energy not needed to overcome the inertia of the winch would be available to put into the shooting arm (instead of being wasted pulling on a frame member)?
