I got the 56 LHT with 26 inch wheels and have been very happy. I wanted the option to run wider tires and also liked the slight theoretical strength advantage of the 26 inch wheel. In two years of hopping curbs and heavy loads, my wheels are still true. The 26 inch wheels have been great on trails with 1.5 inch tires and I will probably go wider next. I also have no toe overlap issues with it. I really am happy with my choice. That being said, I am sure you would have no issues with 700C wheels too. For me though, with the LHT, the 26 inch wheels are great.
