I too am 6' 3". I always have trouble with jackets being too short on the torso. Is the medium Rab Momentum long enough over your bum when cycling? I also have long torso / short legs though... What's your inside leg?
The Rab is about perfect length wise for cycling, long enough in the back to cover your arse, short enough in the front not to bunch up when on a bike, long arms too.
