Yes - Euroswift, I well remember riding my Dawes Gallaxy from Cheltenham to Newcastle upon Tyne along the old Roman roads and getting terrible neck and shoulder ache from holding my head so far back as to be able to see more than that front axle... It was a pain over the four days the journey took me. Also, I never feel so fully in control on drop bars as on flat ones.
You and I have a different problem as regards fitting on a Moulton TSR. I am a full 20cm shorter than you are. On the TSR30, I felt a bit stretched out except when I had the stem turned up at a crazy angle. Fortunately, the stem was very adjustable.
This bike now resides in luxurious circumstances at Sesamecrunch's bicycle museum in California, having been collected from the UK and personally escorted by him - probably with its own seat and accompanying bicycle mechanic in case it became alarmed at the drop in cabin pressure during the climb phase of the flight.
