Technically T11's have a 250 weight restriction. For the OP - yes we remember the quote - the Chris King option was the one he seemed most interested in and I have nothing bad to say about the R45 hub setup and it should withstand his weight. IIRC we also offered up Shimano hub builds on the similar setup. Tiagra actually ends up being a great value for the price point but the weight is added in with the steel hubshell.
The Dyads are actually a really well performing rim that ends up acting like performance style rim under heavier riders. I have been using them both for performance touring applications as well as heavier enthusiast riders for a while with great results.
