Your approach of using only film caps is a good one. I have a friend who dislikes ceramic caps, and the smaller sizes of X and Y caps are usually only made with ceramic. I will have to try your combination.
Thanks also for confirming that the Vishay caps are nonmagnetic. This seems to be important.
Finally, I'm in the middle of an evaluation of the resistor value that works best. My 120 ohm figure was calculated from crude measurements of some house wire cable. A lower value, such as 100 ohms, may work better. Keep in mind that your close spacing of capacitor values will result in a lower net resistance over most of the frequency range. Stay tuned.
