Love mine for all year round no fuss riding. I commute off road and it goes even when I can't actually see any of the drivetrain for mud. I've just changed the chain after 3 years, it was still working fine but an oil change was due so I decided to change it reverse the chainring and replace the rear sprocket. I could have just reversed the rear sprocket as well but went with a new one as the outer of the sprocket forms a seal with a gasket and after 3 years I'd have been running a far from perfect surface against the gasket potential wearing it faster and the tool required for replacing it is more expensive than a new sprocket.
Apart from the very low maintenance what I really like is the ability to change gear when stopped. You have no idea how useful that is until you have it. I have a Thorn Catalyst which is similar to the Enduro but has longer chainstays to allow a rack to be fitted and is V brake specific. My bike is very heavy but then it does have Magura Oder forks and a Son dynamo hub as well and being less than 60kg myself I do feel that on the ups. If I were to go buy a bike with de-raileurs then it would have to be with a frame that I could easily put the Rohloff on. Whyte 19 is top of my wish list at the moment.
As for the weight shift to the rear I don't see how it differs from the weight shift to the front that front suspension brought. It's just something you get used to. I would think the point of balance on a Rohloff hardtail was very similar to a fully rigid bike.
