I'm 6'2 and have ridden my 18 lb 753 bike when I weighed 200 and it's definitely my favorite steel bike. I have 7 steel bikes ranging from unknown lugged Swhinn steel to double butted Renolds 531 and the 753 bike. I would just talk extensively with the builder about how you intend to use the bike and see what he says about it and go from there. Personally, I usually want the lightest I can get for the use and if working with a builder I would want a very close estimate on weight. If the builder was more concerned about strength and seemed to think weight was unimportant, then I might look elsewhere but intended use is pretty much everything. For example, I do like light, but I expect heavier on a bike intended to carry stuff or be ridden rougher. That's why I own a dozen or so.
