I know, from owning SIS, that Suntour Superbe is equally as fast as SIS, and the VGT is pretty darn close. Friction shifting is an art, and it takes practice, but once you get it down it's very fast especially the Suntour stuff. One of my bikes has Suntour ARX and it's not as good as the old VGt was and obviously no match for Superbe. I am seriously thinking about removing the ARX and put my spare Superbe on the bike. Not sure what went wrong with ARX because Suntour had the best derailleurs, but they did make a few bad ones.
