My only concern about the WT is possibility of severe toe-fender overlap. There doesn't appear to be a lot of clearance up front. Toe-overlap with the wheel is fine, but toe-overlap with a fender can be dangerous. There is some chance that the fender will get caught on the wheel and get sucked up along with the wheel and forced through the fork. This can happen even with slick tires. It happened to me once. My foot gently pushed the fender into the wheel, the fender got sucked through the fork, and locked the front wheel, ejecting me headfirst over the bars.
I have never ridden a WT so I can't say for certain that toe-fender overlap is an issue, but I would be weary of any bike that presented an extensive toe-fender overlap situation. There are other options, such as the Fantom Uno or the 925, that appear to have slightly shallower headtube geometry and appear to be more accommodating.
Perhaps someone who owns a WT, with fenders, can comment.
