I have pretty wide shoulders and I found the Bridge was fine. I weigh 210 too, but I am only 5'10" too. Bridges are easy to make and you would do well in one with your weight. I have made three of them so far and I have altered a JRB as follows:
and here are some shots of others:
I personally like having no end caps on the bridge. I made one to Grizzley Adams specs and a couple more the same size and parabolic measurements as my JRB. For me, I like the narrower cuts of the JRB. The narrowness of the flat laid body fabric as it's cut makes no difference as to how they feel when you lay in them but it seems to make a difference in has easily it is to get in and out of. I like short sides so I can see out easier. Hope this helps some.
