A tourer would be strong enough to cope with a bit of rough trail riding- and a CX would be able to take racks and pannier bags for a bit of touring but would you ever decide to do those 5 day fully loaded tours?

Been looking at a Giant TCX http://www.giant-bicycles.com/en-US/....1/7315/44077/

But the main consideration is how the bikes would ride. Both would be different to your Madone so get a test ride.

I am afraid this is a biased opinion. I would not have a use for a Tourer- but I fancy getting out on those hills on a CX and giving it a try. Then If I would prefer to use the MTB up there- I would still have a bike I would ride. A heavier Touring bike would just sit in the shed.
