Hazeltine does not have much RTJ Sr. left but it is only a brute if you play it from tees longer than your abilities will support. If you play it at a length you normally play it is pretty enjoyable. A lot of the yardage is hidden in par 3's and 5's. The greens are receptive to a reasonable length iron shot but nearly impossible to hit from further back.
My general impression is that his non-championship courses are pretty fun to play -a bit of a transition from the Golden Age to the dark ages.
