I was hesitant on the 3/8" wide braces all around.... I know the "Standard" OLF OM braces are 1/4" wide -- so the 3/8" braces are about 1.5X stiffer... which is a whole bunch.
I tried to compensate for this with the gouge -- scooping out material so the brace had a wider but very thin footprint. If nothing else, this should help keep them from telegraphing.... which I really don't think would have been a problem anyway with this top thickness.... If the top was like 0.080" thick... maybe it would help.
Thanks for the advise on this.

You can not base the additional stiffness of a brace based only on it's width. Height is very important. In fact height adds more addition stiffness (section modulus) than width does. a taller 1/4" brace is likely to be stronger than a shorter 3/8" thick brace in the vertical cross section modulus
In other words within a given range you gain more section modulus strength by increasing the height by “X” that increasing the width by the same “x” value
