Adam:
The Castle Course may well have been designed with that in mind. I've said before that a lot of the criticisms of it [blind hazards, having to aim well away from the hole to get it close, unexpected bounces] could be said of The Old Course, too.
However, I don't think the short game shots around the greens are very similar at all. There is a lot of short grass around the greens, but because the course was built on a sloping site, when you're off the green you are usually way below the hole ... you're putting up to something over your head that you can't see. So, the scale is entirely different than The Old Course.
