I know the feeling, I purchased my Graham Weigh this time last year. For a 531 competion it was expensive but inline with the elite frame builders ( Mike Kowal built mine ) all worth it though it rides like the wind.
Hi Mark, I'm 6 2 and my ideal seat tube is 24 1/2" so I think this could be for you. Is VCR close enough for you to visit and try the Graham Weigh for fit and ask about a part exchange? Good luck with finding the right bike for you.
If I remember correctly from his autobiography Chris Boardman had a lot to do with Terry Dolan, even working in his shop. Listed on Hilary Stone is a Terry Dolan, Cougar. At 25.5 inch it's a good fit for me, maybe one day.
