Thanks. That was very interesting to me. I'm on a very obsolete z9BC, which is "dialed down" to 2 CPs and a group capacity of 35. And the chance of us ever upgrading approaches zero from below (as we used to say in math class). So I often come up with ideas that just aren't relevant to a current shop's needs.
