it appears that topre has worked with cm on the novatouch. also, the topre stems are the same size (and swappable). theoretically, we should be able to get after market mx compatible topre stems, now that its easy enough to duplicate. why aren't we seeing or hearing about these? instead of cannibalizing from a novatouch, we should be able to just buy the stems in bulk. i'm sure a lot of people would be interested in this, if they were available.
