Sounds like you're describing a difference in bottom-out sound. The Filco is solidly constructed with very little give or absorption, so it makes sense that the bottom out is noisier. You say you didn't like the orings on your Filco, were they thick or thin? You can't tell just from the colour, there are thick and thin red ones. If thick, perhaps give thin ones a try. Or if you are interested in some modding work, desolder the switches and put a thin slice of oring in each switch inside the little tube (trampoline mod, 1mm or less should do the job with Blue switches). The advantage is you can adjust the feel by changing the material used and the thickness.
