I have just bought a second hand Raven Tour.
I am very pleased with it. The hub is excellent, as many have found before me the excellently spaced ratios and the ability to select them in order makes this type of hub much more user friendly than 27 speed deraileur. I only am able to manage short rides compared to you proper cyclist (trying hard). But I love the bike and the hub.
So if you are thinking about making the change to Rohloff.......go for it. You will not regret it.
