I might look more to say Zinn Cycles like the Clydesdale brand he makes (or someone makes for him that he designs). Being 380+ requires a lot more out of a frame and components and Zinn understands that. Surly makes fine bikes as did All-City but I think QBP would likely say they are unsuitable at that weight. Obviously it will go down but at this point I would make sure it can handle the weight easily and make sure you have very well built wheels from someone who knows how to do it and you have a frank conversation with them so they know what is needed.
Good luck on your journey!
