I have some tactile grays in my ergodox, with 100gr springs from Spirit's 1st spring-only GB.
I have to say I don't like it. Not because it takes too much to actuate ... I have 100gr springs in the nearby clears, but the tactile gray, even natural, is a bit too 'mushy' for the feel I was hoping for. 100gr manlyclears are mighty stiff, but I happen to like them.
Of course, the pinkies don't have that ... browns, and off-homerow they have 50gr springs (also from Spirit). So, whatever. I believe that for the current run of springs, the 100 & 120gr versions didn't reach MOQ. No surprise they're a bit of a specialty item (and I guess I'm just special that way).
