The interesting thing is the work they are doing on #8. One of the holes most used in publicity photos, it's a par 5 of 600+ from the tips and over 550 even from the white tees. A three short hole for everyone. The drive is downhill to a left-to-right fairway. the second shot is more downhill and the fairway runs out around 150 from the green. There's a flat spot you can play to further back on the left side of the fairway, around 180 out. Basically, after 2 good shots, you either have around 180 from a flattish area into a green that sits hard against a desert wash, or you have 150-160 from a downhill lie. It's a really, really tough hole. They've been pretty mum about exactly what changes are being made but I'd guess trying to flatten more of the second shot landing area and trying to expand turf options as much as they can while preserving the wash.
The new greens will be a plus, as well. The Saguaro has had much better surfaces since it opened.
