I associate twist shifters with hub gears.
The Rohloff I tried worked fine, although it required a bit more grunt to twist than I would have liked.
The NuVinci constantly variable hub has, out of necessity, a twist shifter.
That can be quite hard to shift, which is probably one of the reasons they have produced an electronic version.
I've tried basic Shimano twist shifters on derailleur bikes which worked OK, although I would like to try the bike before buying it, just to be sure the twisting effort wasn't too much.
