Which to pick.
on whether one or two piece are better
I think the preference for two piece is because the
manufacturers use two piece, if there is a difference at all
the absence of the glue will allow vibrations to pass
through the 1 pc blank
aesthetically the one piece are beautiful with the figure running across
the entire body but may look a bit odd to someone used to standard guitars.
Price wise the one piece blanks go through my drum sander which is much slower
and makes them more expensive.
the difference between standard and flawless is not huge in the Sipo as it is almost always
virtually flawless anyway.
regarding the difference between Quarter sawn and standard I reckon the difference is largely aesthetic
with quartersawn you get the grain as a series of parallel lines where the rings are cut,
standard tends to show the grain more akin to a contour map, both are nice and it's a matter of taste.
Thickness wise the blanks are all dressed so the amount needing removed is minimal
so go close to the thickness you need.
