I generally like the idea of narrowing fairways at a certain distance or running out of fairway on a gently legging hole. However, it works better if there is a natural feature (or very well done man made feature) which narrows the fairway. So in this respect it is similar to the Ben Hoganism. You shouldn't use the driver off the fairway more than once a game because one gets a lie which can accomodate a driver only once a game.
For those that think narrowing the fairway at 300 yards or whatever prohibits the average player from making the carry in two, whatever happened to the forward tees? If pros have to be deadly accurate at 300 yards, the average guy need to be deadly accurate at 200 yards. Since when did the average guy play the pro tees? If folks play the right tees, there is no problem with narrowed fairways. A bit of a no brainer really.
I also like the idea of centerline bunkers, but I am not sure the general golfing public on either side of the pond approves of them. Again, this should not be overdone.
I don't even mind trees being utilized, so long as they aren't out of control. A couple times a round is plenty and if there is a lovely old tree being used, I readily appluad this. However, the hole still needs to have merit when the tree eventually disappears.
I also really enjoy diagonal carries (creeks are particulaly good), especially when the safe carry is the worst position to be in if a shot is played too conservatively.
Contouring of fairways is also very clever. However, most of the man made humpty bumpty I have seen doesn't look right. Also, I tend to think that pros generally don't struggle much with this situation unless it is windy.
