Recovering an old thread, hope its better than starting a new one?

Maybe there will be more opinions...
I'm facing the same dilemma as the OP. I own and ride Fazer 600 2006, took her for a bit of touring around Europe (but paved road, like Pyrenees and Norway). However, next year I'm planning to set off on the solo RTW adventure for a year or so. I do not intend to do any serious off-road and the vast majority of the roads will probably be paved. So my options are:
1) Keep the Fazer.
Pros:
- I already own this bike. I love it and I know it.
- I owned it for a couple of years and didn't have any significant issues. I've put some extras that I need already.
- I've researched a bit about equipping it for RTW and looks like I can get most of the items for it, e.g. handguards, hard cases, suspension, e.t.c. Bashplate seems to be an issue but if worst comes to worst I'll build a custom one.
- Its fairly low value which is good for Carnet purpose (and its not super-shiny-new so hopefully less chance of having it nicked).
Cons:
- Limited off-road ability (pretty much next to none, apart from basic gravel and firetracks)
- Limited range of accessories (e.g. when comes to panniers, the only rack for hard panniers I've found was from HB),
- Sensitivity to crap fuel as mentioned by some.
2) Sell Fazer and buy something more suitable e.g. VStrom.
Pros:
- Wider range of touring accessories available,
- More off-road ability.
Cons:
- Its a new bike that I don't really know,
- Its likely to be more expensive for Carnet.
I'm thinking about it for good few weeks now (well, not constantly

), so wanted to grasp some more opinions if possible.
Thanks so much in advance!
