The issue with Laurel Valley is turning off the H20 -- the place is extremely L-U-S-H. When you have tee shots hitting and then backing up in middle of summer you have a major problem in terms of how the course should play. I truly believe that if a speck of brown ever came up the powers-that-be would rush in a mano-second and straighten it out pronto!
The layout has demands from the tips as others have explained, but I don't see much character with the course beyond the difficult quotient.
No doubt about the facilities as it's Corporate Alley for all the execs from the greater Pittsburgh area. Laurel Valley has plenty of brawn but oh so little in the character area. For my $$ I'd stay in Pittsburgh and trek to Oakmont, Fox Chapel, Pittsburgh Field Club for a better overall course. But, if you want the pomp and circumstance that goes to all who play Laurel Valley you'll be treated in a very, very first alcass manner.
