I actually prefer Portrush Valley to Dunluce. In any case, the pair are totally different and make a very good team.
I also think Burnham's second course is well worth the effort if playing the Championhsip course. There are some cracking holes to be had for very little money.

I cant find it on the search but I am sure we had a thread on this....I may have even started it??
Agree with Sean that the Valley is a success as a second course but not sure I would go as far to say it is a stronger course than the Dunluce.
A few people prefer Gullane No. 2 to No. 1. I think the back 9 at No. 2 is as good in places as anything at No. 1, and it has been said before that No. 3 has a good set of greens.
I enjoyed the Weyhill at Saucon- it could be that they have 3 really good courses! Not that I have played the others but I have heard good things.
