I'm 5'-8" and have never had the chance to try a WSD as the shops here only carry them in small sizes. I got a good fit on my Rocky Mountain Sherpa touring bike (size 51cm) right off the rack, and recently tried a Look 566 in size 53cm that only needed a slightly shorter stem to be perfect.
The classic sport tourer of the 70s isn't so common any more, but the Salsa Casserole, Soma ES, and Jamis Satellite (comes in a wsd version as well) are some current examples. Touring bikes are rarer but still made by many manufacturers. The touring forum is a good place for suggestions.
Many people now ride 'cross bikes, they seem to be the new sport tourers. You can put fat tires on them for touring and rough roads, or skinny tires for road riding.
