Hi,
I have a 586L Raven Tour with the comfort bars. I am 6 foot 182cm approx. I find this the right size, it is larger than the Thorn guide suggests for my height. So if possible try the bike before you part with all that cash, although there is a 90 day return on the Rolf hub version if you go that route.
Rolf hubs are excellent if you have not tried one yet. I am still getting used to the comfort bars as yet undecided as I still get numb hands with them.
Good luck with what ever you choose, they are a fine machine.
Roger
