IIRC, a number of teams found something more in the 30s was more effective in 2006, once spin effects were factored in, and given that the target sloped into the field. But if you want a high arc for a more vertical shot to the hoops this year, you might want something in the 60s.

Build a mockup of your shooter (once you've answered your first question) and try it at different exit angles in an open area with a hoop under the landing path. The answers you get might surprise you.
