In my one play at Pebble Beach (I also had one play at Pasatiempo on the same trip) I don't recall the greens at PB being particularly bumpy as Kalen alludes to but then I don't recall them being particularly good condition wise either which is perhaps understandable given the amount of play. I do recall though that there was a collar of what I'd call rough round the greens and between the greens and the greenside bunkers and I think that is what Peter was probably referring to. The effect of that was to accentuate the smallness and perhaps lack of contour of the greens.
In fairness Pasatiempo had something similar round their greens but at Pasatiempo size, shape and contour of the greens providing great interest, as much for the approach shots as the putting. Chipping, not so much because of the rough as I mentioned.
In contrast there isn't that level of interest in the greens at PB, which is not to say it is boring but that it's just not inspiring.
As for the notion that Pasatiempos greens don't stand up to "today's speeds", should the speed dictate the design or the design dictate the speed ?
