if youre still interested, i bought the r12 too. im 6'7 so i feel your pain. dengfu is the only retailer i can find that makes 61's. the next highest was either winspace, yoeleo, or ican, who made it in 59 (MAYBE 60 depending on the frame, i forget, def not 61). i fit in a 61 but im all upper body, my inseams equal to like a 6'1 guy. so youd probably fit nicely in a 59. for my next build (if i sell my current fm098) i might get an ican a9 in 59 and hope i can squeeze my ass in it.
