I had a first year of production LHT, but mine was defective. Surly refused to warranty it, I eventually put the frame in the metal recycling bin. I have a Sherpa (derailleur bike) and a Nomad Mk II.
I do not know what the weight rating of the Raven is, but I think it is similar to the Sherpa. I have used my Sherpa on routes that would probably have worked well with a non-defective LHT.
Nomad is rated for something like 60kg of gear not counting weight of rider. That is a LOT of stuff. Bike unladen is roughly 20kg, which is pretty heavy for a bike.
I wrote up my Iceland trip on my Nomad here if you are looking for some real world examples with photos:
http://thorncyclesforum.co.uk/index.php?topic=11917.0My advice would be to not get the Nomad if the Raven will be sufficient. My Nomad has S&S couplers, my bike with the S&S Backpack Case will exceed most airline weight limits, I have to carry a few bits of the bike in my other luggage.
Do not get me wrong, my Nomad is a great bike. But, you will notice it is a heavy bike. My next trip will likely be with my Nomad, but that is because it has the S&S couplers, my Sherpa would be a better bike to actually use on that trip, but getting it to and from in a full size bike box would be a hassle.
A side note on the Nomad, it will also work with a 100mm suspension fork. I do not have a mountain bike but I have used my Nomad with a suspension fork on a couple trips that would have been more appropriate to use a Mountain bike. That is not something that you can do with the Raven. Some on one of those trips here, skip down to the post that has large text that says UPDATE:
http://thorncyclesforum.co.uk/index.php?topic=11321.0On the Rohloff, new users often have the cables to tight, you need plenty of slack. And do not ford any streams that would result in submerging the hub.
I use drop bars on most of my bikes, Thorn recommends flat bars on the Nomad. After my Iceland trip, I moved my shifter location to the end of the handlebar with the Hubbub adapter, that allows me to have both hands on the bars for steering in difficult terrain while one hand is also on the shifter.
Since I have not used a Raven, I can't comment on the different shifter cable setup on that, I have only used the EX box that I think works quite well.
