Acoustic Guitar Construction

From their website:
"Solid lining has a huge impact on the guitar, creating a body with tremendous torsional strength. That allows us to build a lighter guitar, yet one that’s stronger and livelier. Thinner than traditional kerfed lining, the guitar top has more freedom to vibrate. "

Any idea how much thinner they are talking about?

From the pictues I've seen if appears to be about 3/16" +/- vs the normal 1/4" +/- -- the whole idea is to allow the perimeter of the lower bout to move more freely. Taylor thins the inside edges of the sound board as well others (including me) taper and thin the outside from about 1" in from the perimeter.

Ok, thanks.

Off the top of my head (very, utmost top) it seems like you could just add 1/8 inch of width to the lower bout and get the same effect.

Are solid linings really necessary for building light? Taylor is a respected factory, to be sure, but like every other factory, they have a marketing area. I guess I'm wondering how much of this is making a verbal case for their product and how much of it is actually something one can hear?
