Impossible to answer that really - you could try contacting Martin Blackwell for advice, but really you should just try the Savarez strings and see if you like them.

Action at the nut is measured by fretting at the third fret, so that the string is stretched between the second fret and the nut. Now check the gap between the string and the first fret. This should be about 0.25mm for the bass E, the A and the G strings, and about 0.1mm (a piece of paper) for the D, B and top E strings.
am i reading this right?
.25mm for e, a, and g
.1 for d, b, e

or does the person mean .25 for e, a, and d
and .1 for g, b, and e?

It is correct - the G string needs a little more clearance than the D string.
If you want to be a little more precise, then these are the numbers I use for each string:
Bass E - 0.25mm
A - 0.2mm
D - 0.1mm
G - 0.2mm
B - 0.1mm
Treble E - 0.05mm

thanks james, that clears up a lot. i have a bunch of books on guitar set up, but once it gets into the classical guitar section. the information just doesnt seem right, especially visioning to my fingers. how would you measure .05mm - with a feeler gauge?
ive been currently using a string guage ruler (like the stew mac kind) for saddle height but the lowest measurement it goes down to is .25 mm
i know sources say enough to stick a paper under it, but thats hard to measure considering the paper fits under all the strings.

Feeler gauges are best, but you can get close enough to the 0.05mm just by getting the string as close as you can to the first fret (when the string is pressed down between frets 2 & 3) without it actually touching.
