I'd go pretty heavy on it.
The shorter the scale, the fatter the wire. Well, if you want good tone.
Not to mention a heavy-gauge 3rd can also serve as "piano wire" for those "pest removal" operations that certain Family Men are wont to engage in
And they can slice open a finger pretty easily, too.
If you're going over 10, find a wound 3rd. It feels weird at first, but the wraps aren't as likely to hack off a finger unless you're doing that 'Family Man pest removal' I mentioned earlier.
I, personally, would start with 10s on the short scale and see how you like the tone and feel
