Channel over the f wing

I have always thought about a very light scoop on the f hole wing of Stradivari's violins.  The next two photos are details of early Strads, the first photo is a Nicola Amati.

After listening to last year's Joe Curtin's lecture about how much the wing of a violin move and affect sound looking at these photos makes me want to carve more wood there where the fluting begins.

This image is from the pristine Messia.  Look at how different is the channel on the purfling from the decorated Strad below.  I particularly like the image below because the varnish looks "fat" with the surface texture very close to the original.

Hi
Do you think del Gesu also made pronouced channels like Strad?
