I'd mostly be riding with KTM 890ADV or AT so I don't need a true singletrack weapon which is why I'm looking that way.
If you're as good a rider as your buddies, then anything in that class will do: F800GS, F650GS/F700GS twin, V-Strom, CB500X, Versys 650, Tiger 955i etc. From your description, it doesn't sound like off-road chops are as important as being comfortable on the highway.
if you're not as good as your buddies and you're spending a lot of time off-pavement, opt for a lighter thumper.
