Re the nut issue -- If you
don't wanna' file the nut, then
I guess the Roto's are outta' the question (they're even bigger)
LaBella: .060 - .128 Rotosound: .065 - .135
(you knew this was comin eh?

) There's always Thomastik-Infeld
nylon cores. Totally different feel (
VERY low tension) with a
super-sweet tone. Not as "crispy" as other acoustic strings
with their hexagonal steel cores. Another "drawback" is the price.
~$60USD for a 5'r set. If you don't like `em, you're out some $$$.
Anyhoo, you shouldn't have to do ANY nut filing with these
(.041 - .118).
Length problem...I noticed somethin' cruisin' around Just Strings.
There's a "760N5" and a "760N5-EXL" (extra long). Maybe you
picked up the EXL set?
