31tet guitar advice

Hi Folks,

I'm almost-definately going to have Glen Peterson
do a 31tet refret for my frankencaster.

It seems that a tall and thin fretwire would be
helpful. Does anyone have any tips about this, or any
other micro-refret advice? How about the upper octave,
will the frets be impossibly close together? Has anyone
done an "every-other-fret", or switched temperments for
the upper octave?

Thanks in advance.
