String gauge for 12 Acoustic

[Fedora]

Hey....what gauge are you all using on your 12 string acoustics.
Right now I'm using an extra light set 10-47. Not all that happy with them. Kinda buzzy and limp. I am pretty heavy handed.
Wondering if I could keep the same action and go with something a little stouter and get rid of some buzz and get better sound from the piezo.
Just wondering if the extra lights are a "normal" gauge.
I have a two hour solo gig coming up and I want to do it all with this guitar. I don't talk a whole lot..so it'll be non-stop.
Concerned with fatigue if I go with something heavier.

Thanks all!! Rock on!....in an acoustic sort of way

Don't go too heavy. You should consider the manufacturer's recomendations.

I guess I won't go too heavy. Maybe I'll just lighten my touch.
