I may also be able to dig up a Clear switch with several spring weights that you could try- stock, Grey (I can't remember what weight that is, but it's heavy) and Korean 65g (Sprit gold).
You'd have to cover postage from Hong Kong, whatever that comes to (Google Hong Kong Post if you want rates). PM me as I am not subscribed to this thread.
For what it's worth, I really didn't like stock Clear springs as I prefer to be able to bottom out on key presses. I found that the Clears had a marked ramp out as bottom out approached, which meant that the very last bit of travel felt mushy and had to be forced. When trying the keyboard in a store for five minutes, I was unable to predict this- it was only something I noticed after extended use.
I'd also agree with others saying that testing a single switch won't tell you much. I tested both the stock Clears and ErgoClears as individual switches and woudn't have been able to predict a preference based on the feel of a single switch.
