Hi Toril --
I was thinking about Eileen's comment.
Moving styles is a two way street, but the street has a big hill. Going one way, a bicyclist has to work hard. Going the other way, the bicyclist can glide.

Moving Genos to S/SX is a lot of work because, as you know, Genos has a number of features which are not in the S/SX-series. That requires fix-ups. However, moving the other direction, S/SX to Genos, the S/SX style should work quite well without (much) work.
I'm still using styles that I made on S950, playing them on Genos. They are good enough.

When I have the time, need or inclination, I'll upgrade a style to Genos.
That's the catch -- time. With gigs and other duties, none of us has that much time. So, a quick way to go is to use S975 and port to Genos.
Just thoughts -- pj
