I've ridden with both clubmans and drag bars.  For long trips the cubmans are laborious and I switch to drag bars, lot easier on the body.  For daily riding around the city I find clubmans are fine......and they're fun.  I don't have rear sets but I've often thought it would be quite a bit more comfy riding clubmans with rear sets.  I've heard the same thing that OakBehringer said about superbike bars, thinking about giving them a shot this spring.  Oh, and I've never ran cables through the bars, seemed unnecessary but I think it's just a personal preference thing.
