If i am completely off I am sure one of the nice more experienced builders here will correct me.
Your lithe like build is too your advantage with the build you more than likely only need to concider the height variable - As a well built 6 footer I am having to work out where to add shims into the armour pieces to accommodate the extra girth of my chest legs and arms.
Good luck with the build and wow - a marathon in a full suit after the swim and cycle that's crazy but awesome.
