I went through my IGH phase. All 4 kids got IGH (nexus-7) set ups and my wife got a nexus-8. I briefly tried a nexus-7 touring set up --and even added two front chainrings to increase the range. They're all gone except my wife's nexus-8 and my nexus-4 commuter. I disliked the touring setup immensely. Too heavy for what I got out of it, and way too inconvenient for flat fixes.

As above, I do like the nexus-4 IGH on my commuter, and I'm building a new one. Reliable so far through all weather and temperatures. But that's it. (except I gave all the nexus-7 builds to my neighbors who love their convenience, --except they come back to me for flat fixes and maintenance). I also built up two older schwinn twinn tandems with leftover nexus-7's. That seemed to be a great setup
