I disagree with the notion that one's result on the 15th hole is a matter of luck. In general, there are two ways to get the ball close for each pin position, with the exceptions being the middle right pin on the plateau, and the back left pin. Club selection, shape and trajectory are always important.
The 11th hole appears the consensus choice for least favorite, while I selected it for my favorite. Perhaps I am biased, as I love the feeling of hitting a well struck, longer iron (which only happens about 1/4 of the time for me these days) and watching it soar against the sky in the proper direction. This hole is subtly sloped from back to front, and uphill putts are more uphill than they look, one of the few places where putts at Ballyneal are deceiving.
Steve Lapper made a hit-and-run comment about Sand Hills on page 1, then disappeared. I can't get it out of my head, probably because Steve and I have gone back and forth about the two courses forever. I may start a Sand Hills Par 3s thread, to try and provoke some thoughts about the par 3 holes there. If Ballyneal's par 3 holes are its weakest component, I'd say the same is true of Sand Hills, as well as maybe every other great course, as longer holes to me are by nature more interesting.
