MarchandDeBoeuf, Most important is which of the LHTs fits the best. The major differences are wheel size and the brakes. I don't think there's a "wrong" choice regarding the size of the wheel or brake design. The 26" wheel will be slightly stronger because of the shorter spokes, assuming all else is the same. Disk brakes are better in the wet, but not overwhelmingly so. They would eliminate rim wear along the brake track, in particular if rode off pavement a lot.
