Eric,
Cool post, and yes, Ballyneal's 8th is an awesome par five. I loved the halfpipe fairway, the Sahara bunker complex, the bunker short left of the green that guards the best landing area for the second shot, and, above all, the green. That green is brilliant. It looks very complicated, but it simply slopes one direction, with three tiny pimples placed perfectly to befuddle golfers. The collection area right of the green is superb as well.
However, 8th at Ballyneal is not my all-time favorite hole (despite my 3 there). In fact, it's not even my favorite hole on that nine! That would 7, the great short par four with my favorite green complex of the year.
My all-time favorite hole? I'll have to think about that one for awhile. 7 and 13 Ballyneal are certainly contenders, but there are other ones in the running as well.
