Not sure the 100 chisel plow will have enough tension in the springs to hold with 4" twists. They were designed for soil savers and most of them have a much higher trip pressure than any chisel plow. 3" should work, you may have to slow down depending on HP in front to allow shanks to stay where they belong.
