How about a Surly Cross Check? It's not as heavy as an LHT, and is a good do-all bike. It can do road riding, light to medium weight touring, cyclo cross, etc. The LHT is great at being stable with heavy loads, but unloaded you might not be impressed. If this is a loaded tour the LHT is a good choice, but if it's supported, the Cross Check might be better. However, if it's a supported tour, what would be the problem with the Roubaix? I don't think the frame will get damaged during shipping and if a component gets bent, it'll get bent on one of the Surly bikes as well.
