The reason for the step-down recommendation is because the aluminum flexes
and looses some pitch. Stainless does not.

So -- Here I am; for curiosity sake; asking you if the weight of a ss

fwiw ... I was advised by the dealer to step down in pitch e.g. 23" to
21" when going from aluminum to SS. Never looked into it further, but
a step down would imo reduce stress on the outdrive.
