The Asnes guide reads 10cm taller than height and with my height it’s a bit more than that Thoughts ?
And, as I mentioned in my post, the Rabb 68 page suggests a length similar to your height:
Of course, all of these suggestions are only guidelines, and, as others have said in other threads, it really depends on what you are using these for (e.g, turns in steeper glades vs. long, rolling tours) -- and, also, it depends on your skill level, whether you're carrying a heavier pack, whether you are heavier than normal for your height, etc. But you probably already know all of this.
Looking at your past posts, I would get the 172 if I were you, assuming that you are getting it primarily for touring with lots of turns (perhaps on more challenging slopes) vs. touring with occasional turns (on more gentle slopes).
