Paf, you'd be quite unhappy on the slope!
Particularly when paralleling the slope, one wing can be in the slope lift, with a gust coming along and stalling the other wing completely!
90 degree banks in an instant..
Keeps one's attention..
Sloping should be a requirement to get a pilot's license.
You'll learn more about flying there than anywhere else, and your flight times are limited only your endurance, or the plane's batteries.
Highly recommended to everyone.
