You are just deflecting. I asked you a specific question related to your reply in #101.

You said: "What is the pitfall with having two bi-lateral screws control FS retention? Competing inequivalent torque can cause cocking of the Future Shock inhibiting shock stroking."

And I asked in #102: " What are you even trying to say? How would the two head set set-screws prevent the FS cartrige from working?"

To which you, in #103, replied a snide remark, that is now edited to another snide remark. None of which is actually a reply to the question.
