Gee whiz -a lot of 1930's bipes used swept panels and were stable yet very aerobatic and extremely easy to fly .
I am not any good on textbook theory (cain't reed) but some sweep INCREASES stability.
Your right!
I should have qualified what I said a bit better...
When I think of sweep (for speed type of planes) I thinking in the 30-60 degree area, a bit more than you typical design (when you have that type of sweep to the wings it can get a bit dicey).
