I wondered if the gateron clear stem is smoother than the gateron black stem. I harvested the spring of the MX black and transplant it into the gateron clears to see if it feels smooth only due to the light spring or if the stem was smoother as well. The gateron black is smoother than the 60g gateron clear I just made. However I wonder if by opening the switch and manipulating the stem, I didn't remove the stock lube they put on it (if there is some). If it is the case, then my experiment is worth nothing.
