Maybe I missed it, but if it has not been mentioned.
Yes the wrong fit can increase hand pain. Some of my most comfortable bikes (level top tubes all) are the one with the tallest head tubes. And a shallow drop in the h’bars. I prefer narrow too. Best attempt at a flat ramp to hoods given the bars. Cinelli may not always be the best for everyone, including you and me.!

Really, how much standover do you need??? It’s a ROADIE!
on the subject of most comfortable hoods - ever - for stretching out = Campy 9/10 with rounded hood tops and easy flat ramp. Unfortunately I only have them on my 3 most modern, and a 9 speed retro-mod. Need to look for that in a non-brifter brake lever hood.
