I have seen many a custom geometry frame that may fit the rider on paper, but is thoroughly unrideable in practice. So don't go to a framebuilder who doesn't have a good understanding of geometry.
I read an article by a bike fit guy in the USA describing how he found his colnago uncomfortable so got a frame made by a local builder exactly ( according to bike fit rules ) 'his size', but it just didn't work out as planned. The ride didn't feel right and was reflected in his times.
So he then went back to Colnago who explained ( can't remember exactly) that he should ride a smaller Colnago frame but with a longer stem. I other words the frame is designed to work and he needed to adapt...and guess what Mr Colnago was right, the new ride with an adapted ( stem etc ) frame just flew because the frame was a successful design...
I don't know if there's a definitive answer but thought this an interesting tale...
