Well, I'm about to conduct an experiment on this very subject, so I'll report back when I have more information. I just installed a set of Mitas E07 tires on my Super Tenere; not because of their on/off road capability, but because they are purported to be some pretty high mileage tires. Obviously, that's an important quality for a touring tire. I've put a couple hundred miles on them so far, and found that they are surprisingly smooth on the highway, in spite of their chunky appearance. I don't see any issues with them as a touring tire as far as excessive highway vibration goes. The seem to do fine in the rain, at least as far as my riding style goes. Next month I'm riding from my home in NC out to Colorado, for a tour though Colorado, Utah and New Mexico, so I'll have an excellent chance to evaluate the tire's longevity while doing two-up loaded touring. If I can achieve the sorts of mileages that I've seen reported by others (in the 7000+ mile range), then these will become my new go-to tire, to replace the Shinko 705's that I normally run. I was a Battlewing fan too, and could fairly consistently get 5000 or so miles out of a rear tire with a lot of two up riding, but the Battlewings are on the way out. I love the Shinkos, but for me they aren't a good choice for a really long distance ride; I've gotten as little as 3410 miles on a rear, and my maximum distance ever on a rear was 5225 miles. Mileages can vary wildly with the same tire depending on riding conditions, so mileage reports can be pretty subjective, but reports on the E07 seem to be fairly consistent on their reports of higher mileage. I'm hoping my experience mirrors that.
