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


flexes - I think that's generally accepted; but flexes to the point of loosing
2" of pitch? I find that hard to believe.

On this theory; I'm giong to be way under propped as I had a SS 19 and I went to
an aluminum 17; so on your theory; this will be like a 15 pitch SS....
