David:
Have you played both? If you have, I am surprised by the question. There is no reasonable comparison.
Bart,
I have been to both three times. I was interested in your opinion as to whether the OB and houses at Merion is a negative or not because I wanted to understand more about where you were coming from. I was not suggesting that the two courses were directly comparable but a comparison of the features of both would help flesh out your opinion, and explain exactly what it was about the OB at Pasa that you did not like.
Personally I thought that the OB problems at Pasa are overstated. 6 has a good green and a really good tee shot. The second shot is not ideal but on a course with many 50 yard wide fairways, demanding the golfer to play one shot straight down the middle with a bit of pressure on him is not an horrendous offence IMO.
And 7 has a really good green. Again, not an ideal tee shot but the fairway is 30 yards wide on a 340 yard hole. Does the course ask too hard a question, only allowing an unhindered approach shot to the player who can play up the left or draw the ball into the middle of the fairway? Sure, if every hole was like these two, the course would be not so good (I guarantee you that there are some highly regarded courses with 20-30 yard wide fairways though), but variety is the spice of life and a couple of demanding shots is a nice balance to the wide fairways on offer throughout much of the rest of the course.
If you were comparing the course to the very best courses in America (say Sand Hills, CPC, Pacific Dunes, NGLA, etc) then marking it below these courses because of the 6th and 7th holes is fine.
But I am unsure why you would mark it down any more than to a step behind the very best? I loved visiting Garden City, MPCC, Bandon Dunes, Old MacDonald, The Creek Club, Kingston Heath, NSW, Swinley Forest and Sunningdale. But there is no way I would prefer to play any of them on a regular basis over Pasatiempo. I struggle to see how these courses are rated far superior on various lists. Pasa has too many great holes and too much variety to be thought of lightly because of a narrow couple of shots.
