gomeler, What's the base thickness? Kinda agree with Dave-gota have mass. I like the idea of 2 suction lines, and then what "Y" fitting. Like you said, drop the lid on top of the pins and see what happens. Keep us posted This was my last one and it had a
6mm base and was 170 grams. My findings were each increase in mass = better performance staying around 6mm for the base....
