He stated the wings are both at zero. IMHO that indeed applies to your first post.
But, I will also agree it does not apply to the rants that are your responses to his post.
Now if you want a more specific response to your original question, you need to provide more information. For starters:
Are the wings the same area/size?
The top being swept, is the bottom then straight or swept also?
Which wing do you want to stall first?
Do the wings use the same airfoil?
Are the wings staggered?
Regardless of the wing planform, zero zero is always a good place to start. Alternative would be to add a degree or two to the top wing.
