As far as reentrant goes, a notch away in size is also a notch in pitch, so a size smaller can be tuned in double reentrant a tone higher.
So that is really not an issue. I use double for most solo pieces, but some sound persuasive in single. My solo instrument at 465 in A is too high for single reentrant to sound good, at 77cm. It would work at 415 or 392, however. dt To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
