I've previously owned a L32, and I've also owned and still own a fair selection of Avalon guitars. IMO you can't go wrong with the A sized guitars. They are not quite as big as the L series, but they are bigger than 000 sized Martins (I think), and have a deeper body. They can be loud, and they can be subtle.
The obvious choice would be the A32, but as you've already got the Spruce / Rosewood combination it might be worth thinking about a different combination. I have a Spruce / Blackwood model, and it is incredible. It's probably the first guitar I've owned that I
know I will never sell. I also have another A sized model on order, which should be a bit different....
I've had a S12 guitar from the smaller bodied range - and to be honest it sounded excellent - great tone and volume. The only thing is I found it physically too small for comfort.
Have fun thinking about it, and let us know what you decide....
