I have Kailh Speed Coppers and quite like them. Their tactile bump is at the VERY top of the keystroke, so it provides resistance immediately, and then drops off, and then the spring ramps up. You can check the force curve on Input Club for yourself--it's very unique for an MX style tactile switch. The tactile bump itself isn't very strong, but I haven't been able to press past the bump without activating the switch. The bump kind of serves as a preventative for accidental keystrokes with such a high actuation point. Only thing I think I'd prefer is a very slightly lighter spring, but I like very light switches in general, and this one is already very light.
