Hub geared tourer - On-one pomp versa 11, Dawes Nomad, roll my own or something else?

I've read similar things from MTB'rs, and Fatbikers. These guys tend to run a far lower GI than the hub is intended for. Yet the A8 seems to cope well.

Would'nt surprise me if the latest Nexus 8 hubs had the Alfine 8 guts in them, now that alfinw has gone to 11.

The only differences I was aware of was the alfine 8's roller clutch and its insane 135 oln + tapered axle. Iirc the red band Nexus had the roller clutch, so was effectively a 130mm Alfine.
