Interesting. You might ask the question on the scale forum. I am sure I remember Byron Originals having a Staggerwing kit (large model) that flew quiet well. Someone there might be able to give you the information from that kit.

I personally like the feel of a pattern airplane and would tend to go toward the 0-0-0 setup just to get the better pattern feel. Now if I were at a scale contest with all knees knocking at the same time having a strongly self stabilizing airplane could be really useful.

With the large decalage you will get an airplane that when trimmed for a medium speed 1g level flight will give a pitch up with increases in speed and pitch down with decreases in speed. It will behave more like a trainer in that respect.

A lot will depend on your flying experience level. If you can confortably fly a average aerobatic airplane either setup will work for you. Although you will be able to detect the differences in rigging it will not be a big deal.
