The 3rd and 12th at Deal are all time greats. 17 and 13 are really underrated as are 7 and 5.
3rd green, not so much. Its a punchbowl type which yields the same sort of results an awful when apporaching. The more I play 3 the less enamoured I am with the hole. That said, it adds an element of variety to the set of greens which is important. Same for 12 - its actually an easy green to approach even though its unusual. 17 is a good green, but I wouldn't have thougt its special 13 is a good green as well.
7 though is an outstanding green. This is the one hole that I think much more highly of these days.
All in all, I think you are correct. I am not sure there is a links in GB&I with a better set of greens than Deal.
What do folks think about Pennard's 16th - or is it too severe?
I agree, Prestwick's 3rd is excellent - it just out of the humpty bumpty fairway. Same for the 9th at Sandwich, don't think #11 is very special though. Lahinch's 9th too is very good and suits a short 4 very well. Not sure about the 11th as Mac's version is sidelined - I think a huge mistake by the club.
Tenby's 3rd - maybe. I like the 12th more. In general, like Pennard, Tenby has one of the better sets of links greens out there.
Rye's 7th puzzles me as well. I think there are better plateau examples such as Tenby's 12th and 3rd.
