Thank you very much, quite a complete answer.

Regarding the Troll/Ogre, right now I'm looking at a more classic bike, dropbars, cantis, etc. I had an Ogre a couple of years ago. Very nice bike, but quite uninspiring. There are pictures of it somewhere here in the forum. Sold it 8 months later.

I find quite intriguing all the reports of the CC being so much more flexy than the LHT under load. Surly says the the tubing is the same on both, except the CC TT which is of smaller diameter but thicker walls.

My normal solo touring load is a set of front panniers on the back, a drybag on top of the rack, a Tangle frame bag and a MULE backpack. Tent goes on the handlebar. Sometimes I carry a large amount of groceries, which my Ogre and Pugsley used to do without a blink.

Regarding wheelsize, I'll go with 700c
