I have the smaller of the two 747s. I am 6'7" with a 36" inseem. I actually think the frame may be too large for me. Definetly should fit you well. Dont think you have to go for a super big frame. The 200mm cranks are the critical thing. A tall frame with 175 cranks is just ridiculous. And when the cranks are longer, the seat tube and reach can also be shorter.
