OP...you need a comfort geometry with a a more forgiving head tube to top tube ratio to compensate for your long legs and short torso. I am in the same boat and we are the hardest to fit without a big drop. Used Roubaix or OCR...lots of new choices as comfort bikes are now starting to pop up everywhere. You don't need custom, you need an off the rack comfort geometry. The Look 585 Optimum in XL would be just the ticket but they aren't showing up discounted yet. When they do, I am going to try and grab one....retail of $2600 is too much.
HTH.
