Regarding scrubbing points, we are sending you a simpler scheme which we think has theoretical defects over that you have, but may work equally well, or even better, from other points of view. Regarding the rocker spring, we are sending you a new scheme which avoids local stresses in the ends and facilitates removal. We hope you will get these two single and small pieces on test at once, and also thin the scrubber which you have so as to give still more motion, to see if either would give still further improvements.
