Doesn't Idlewild have like 10 different basket types? It did when I played it. That course is "considered" a top 20 course in the world.
This past summer, when I played, there were technically three. The original 18 had rusted out light green Mach IIIs, the lettered holes were Discatchers, and the practice basket was an extremely weird homemade design.
However, all the holes and the practice basket are Pro-28 Discatchers.
