Crystal probably has the most tilt with speed that I have ever seen (including #1, #2, #10 and #11, although #11 is tiered). I think that #2 and #9 at North Fulton in Atlanta may have the most actual slope, but the greens run quite slow. Some of the greens at Baltusrol are quite titlted (e.g. #2 Lower, and from the looks of things, a number of greens un the Upper). Peachtree in Atlanta has a lot of tilted greens with speed (mostly back to front). #3, #4 and #8 at Peachtree imeediately pop to mind.
What about #18 at Shinnecock. I played that hole with an East wind, and you had to just tap the ball sideways to feed a 40 foot putt all the way to the hole from the back of that green (it took about 15 seconds for the putt to stop). AMAZING! #11 also has significant tilt.
