Juststrings has "High Tuning" sets; I did the same (pilfered from 12 string sets) but won't in the future.
I did break the "G" string (.008 on the light set I have), but that was during the saddle making process.
The constant tune up, tune down, pull the bridge pin, got to it real fast.
Here's a shot of the completed saddle.
(I know, its a bit out of focus.
Out of Focus, wasn't that a Blue Cheer song, but i digress...)
The "slots" are a no-no, but as you can see the pin holes are anything but equidistant.
A little work on the nut while I was at it and she plays very nice indeed.
I went with a .010 at the "G" in the final setup.
010 - 014 - 010 - 012 - 018 - 030
(went with an .030 "semi flat" I pulled from a Lap Steel 8 String set I bought to get the "right" 6 for my BR-9)
Haven't played Extra Lights (.008) on my electrics since I was a "wee little laddie" (I used to break some of them).
Since settling on .010 -.052 (again my electrics) I rarely, if ever, break strings.
Think I had to "polish" a saddle on my PRS years ago, that stopped that (string breaks).
Bought a set of "hi" for that PRS, might try it on the electric as well...
