There are many bikes you should try.

My concern is "FIT" and getting the right bicycle for you.
Many Touring style bicycles will have a longer top tube as well as a longer wheelbase so that they can accept racks and panniers. If you have never ridden a fully loaded touring bike, try and do so BEFORE you make a purchase. A loaded bike handles different than when it's unloaded.

One of my Favorite Touring Bikes is the Trek 520. Same bike that has been around for well over a decade with little change.

The LHT is a great frame, while a little heavy.

Have you ever thought of a custom Frame like a SEVEN?
