I run 90-110, with the 110 having enough rise to basically keep the same length as a flat 90, so I get more rise while keeping the ETT or reach the same. Nobody has ever mentioned it and I prefer larger frames to get more rise plus no toe overlap. I technically would fit a 56 but no longer buy 56s. I buy 58s. I have plenty of stems so can adjust as my flexibility or fit needs change. I think it is fine. I have a friend who (after a fit) actually uses an adjustable stem. That things looks pretty weird but nobody has said anything. People rarely notice these things, and what does it matter anyway. It isn't their body or their bike.
