I am in the same "dilemma".
Currently have a G650x-challenge. It is a pretty good all-around bike. Can hop on the highway for a quick commute with no problems (10 miles) strap some bags to it and go (lightweight) camping, can handle ATV trails and some single track.
But I miss my ducati
My bro bought a F800GS and sold it shortly after (for a husky 449) it was an excellent tourer that could handle maintained gravel with ease but a pig in true single track. Fun enough on asphalt but not "fast" by sport bike standards.
I stop by the triumph/ducati/ktm shop my buddy works at frequently. If I had the money and time I would have one of each.
My other problem is 2 fresh kids so my riding time is cut significantly. I was going to take a week and just go get lost in southern mo/arkansas but work and kids got in the way. I can't really justify a 2nd bike right now so I am sticking with the X challenge unless someone invents a better all around bike that can do everything better.
