+1. Just for shits and grins, ride all three (Tiger 800 roadie, 800 XC, and Explorer). You might find that the 800 is plenty, or you might like the comfort of the Explorer. Or you might find that you like the bigass dirt bike feel of the XC (it's fun as hell on pavement, it's plenty comfortable for long distances, and it's an awesome dirt road bike).
