I don't know that it's the 'worst' but I think this will spark some conversation for sure.
I present to you the 9th at Cypress Point.
My case revolves almost entirely around the current green speeds and the green complex. Collectively in 2 rounds with all single digit handicaps I've seen someone de-green themselves well over 10x. The biggest offender greens include 5, 7, 9, and 18. 7 is almost unpinnable and 9 is well on it's way there too.
To a top shelf left pin on 9, your approach is blind and the landing area is minuscule. If you go too far left into rough, good luck stopping a chip of any sort on the top level. Too far long and you're toast. Or if you go for the flag it's likely going to eventually release down to the lower level. From there I've seen more than 1 ball end up off the green and back down in the fairway. I've yet to play to a lower pin, but I remember spending an extra few minutes putting up from lower level to the upper and was amazed and how many balls would eventually funnel back down to my feet or the fairway. That's not to say it's impossible, in fact my first go around my caddie aimed me well left of the flag and my wedge shot left me 4' from the pin. The next time I did the same thing only to eventually see my ball release down to the front edge some 30 seconds after I hit my shot. It all felt very much on the margins of playability.
I also think the drive is one dimensional, keep it on short grass or face an even more exacting approach. If you're particularly long I suppose you could go for it, good luck stopping the ball with driver on that green!
If they were to keep green speeds more manageable I think a lot of my qualms would subside.
