Just a comment on 12s chains. There’s the expense factor (a top quality 9s chain is way less than a top quality 12s chain) but ignoring that, if you used the 12s chain with a 6spd cassette eliminating all the extreme chain angles those chains would last even longer and never get the flex/noise issues they develop.
I’ve run 12s chains on my SS with impressive results.
