Drew the black pen on my 210mm. Can’t say there is much of a difference.
See to me, I see quite a bit of difference, especially in potential weight.
Going back to height, for me, that's again a use-case determination. If I want to use it as more of a gyuto, then I want it a little taller. If it's going to be more in-hand type stuff then I want it shorter. But then, for me, I don't really see a fit for a 180 petty. Too long for my uses in hand and often not tall enough for comfortable board work.
