Welcome to the DSC Fathead (feel funny calling someone a Fathead!)
Those types of trips my preference would be the SS. Having said that I commute on a 996 and my theory was buy the bike you love and deal with how you use it, entirely impractical but hey - I have to be practical at work all day and I have kids .....
As you've been cruising the site you'd know that Ducati's tend not to stay standard for too long so things like front sprockets tend to get changed fairly quickly etc - they're pretty much all geared too tall.
750SS has a wet clutch. Not sure about comfort etc as getting onto one after riding my 996 seems pretty comfortable to me
Not much use to you I know but someone who rides an SS will find this post shortly and give you some more useful information.
