It sounds like the OP just wants a Cherry silent switch without the slightly reduced travel that the silent red and black switches have. I've used both, and there is a very slight reduction in the travel (Cherry specifies 3.7mm), but in use, I have no issues with them. The rubber bumpers on the sliders certainly reduce travel less than either o-rings or QMX Clips. If you want a silent linear switch, they're both good options.
