Wouldn't clicky grays be greens? The weighting would be about the same.
Ah, no, theres a big difference between clicky greys (they do exist or did exist but are the rarest switch) and MX greens.
Greens encounter sharp resistence at the tactile bump, then drop off and keep close to the same resistance (it does increase but it's not really a sharp linear increase, it's very light) under the bump, making bottoming out extremely easy after you pass the bump.
Greys (both linear and tactile) have a sharp, linear increase in resistance that keeps increasing sharply past the tactile bump. The tactile bump is also encountered 'sooner' on greys (and clears). So the force to bottom out on a grey is -much- higher than on a mx green.
