Re: The case against scroll "strengtheners"
As well as from the 'added strength' point of view,i've alway liked the addition of a rear headstock veneer,even against a dark neck.
A black rear veneer would look very nice indeed against any light coloured wood. I don't know if this is a veneer or stain on the Collings MF,but it's a real attention grabber,& there's nor reason why the (a) veneer shouldn't (couldn't) be thick enough to give the additional support to the scroll.The sideview on the headstock with a black veneer front & back, would also look very good (IMHO),
