Yes, the 30 foot rise on #5 green is a massive overstatement. I guess it's a mere 8-10 foot rise. If you hit it thirty yards long to the back of the green on a 120 yard hole, you deserve to pay the price. I birdied it the time I played the hole with the pin front.
Also, the hump on #10 green isn't all that severe, and it is there for a good reason, that reason being to add interest and difficulty to the green. You always have the option of hitting your approach on the side of the hump where the pin is.
In my own experiences, I've grown weary of low handicapped friends who complain about this sort of difficulty on a golf course. Here in the northwest US, players are accustomed to long, narrow, tree-lined fairways and fast, sloped, disc-shaped greens without much internal contouring as the gold standard for difficulty. Sure it's hard, and boring.
One of my buddies up here thought that several of the Bandon Trails greens were ridiculously sloped, and had heard that Coore and Crenshaw were already considering rebuilding several of the greens. I doubt it. I heard (again a rumor) they were very happy with it.
Lately my response to this type of whining is "The course has to be difficult somehow, or else it wouldn't be interesting." I highly prefer this type of difficulty, with big contours and fast turf. Similar to Bandon Dunes, I like Bandon Trails a lot, enough so that I will mix in a occasional round there when I go to play Pacific Dunes.
