Big thumbs up from me too for Wolfman soft luggage - top quality, attractive and practical designs and modestly priced compared to a lot of other stuff on offer.
At least one hard/secure storage solution on the bike, such as your top case, is always handy.
If you're worried about the link pipe (which I don't think you have any reason be), then fit one of the small heat-shields that are available, such as the giant loop one...

But I really don't foresee any trouble on the horizon with the setup you've got.
