This is where certain measurements tend to become more important. I have long thighs but short shins, which makes me require a LOT of setback for the saddle and I won't buy a bike with more than 73.5° STA (preferably 73 or less). For you, I would be tempted to say you just need a much longer stem. Since you're a seasoned rider, you have a baseline to start with. Is there something you don't like about the fit on your current bike?
