Bridge radius on a compound neck

[JamesL]

I know this has been discussed before, and I used the search bar, but there were so many replies. So I'm asking again, I working on setting up my girlfriend's new W Strat, and I have my bridge radius tools, but which radius tool should I use? A 16"? a 10"? 13"? I've forgotten so much in the past years.

Being that a Strat has individual bridge saddle adjustment, if you adjust the string height over the 12th fret to where you like it (industry standard is 1/16" to 5/64"), the resulting overall bridge radius should be close to 18". This has been only recently explained to me.
