Having elevated baskets that require getting the nose of the disc up makes putting, particularly when it's windy and there are drop-off's, more interesting. I'd like to see the standard basket have the bottom of the cage be about five feet off the ground. Having mounds that are even a bit higher (5-10ft.) will create the additional score variance due to putting that many of us would like to see. The game will be a lot more dynamic when picking a drive or approach route will require considering which side of the basket will afford the best chance at birdie and/or the most risk of bogey. I believe our game will have taken a huge step forward when budgeting in money for moving dirt to create real greens is the norm. Just another reason for designers to use their budgets to fully create 18 great holes instead of 24-27 good holes.
I don't like the idea of all basket heights at 5 ft. because it will pretty much kill the approach game. No one is going to make runs at the chains from 100 feet or more out because after the miss, the return putt would be all the more difficult. Even standards putts from 30 feet and in that miss on 5 ft. high baskets would end up with comebackers almost as far away. This would be akin in ball golf to all putts from 10 feet either going in, or ending up at least 10 feet out again. And that's just not right.
If anything, I wish baskets were lower
so that people could be more aggressive from longer distances, one of the most exciting parts of our sport. You'd also have the chance for more skip shots holing out, and holing out rollers in places that receive significant snow in winter.
