I have a Black Hole Practice basket, and my mom gave me a Black Hole Pro for Christmas (not knowing I had a practice basket, much less from the same company, but hey! two practice baskets!) and I really like them both. But if they were the primary baskets on a course with a greens fee, I would wonder what I was paying for. Black Hole Portals have got to be it if you're going for that kind of destination course.
So many courses, even in the top 10, are still free. So if you're charging a greens fee you definitely need something more than 12 holes to offer, or they better be the each of the 12 best holes anyone has ever played. There are only a handful of places that charge that much or more for greens fees and I'm pretty sure there's at least 36 holes, sometimes 54, on the property (Selah, IDGC come to mind).
