RE: Designing a plane just for the wind
The Hooker is a good windy day plane. My favorite was a Ultra Sport 60. I flew it on days I would not unload anything else. It was also the first plane I drug the rudder through the grass on. It was so stable (the faster the better) it just did not bob around in the wind like a lighter plane with a thicker airfoil would. Some other good designs for wind: GP Patriot, Sig Cougar. There are a few others I just can't call the name on.
