Formby is always a treat to play. Yes there are some visually weak holes such as the first and eighteenth but they are a very small minority. The majority of holes are well separated and you often do not see other players. The par 5 third requires you to make decisions on every shot, from the tee do you flirt with the heather on the left, the staggered bunkers or the trees on the right, assuming you've hit the fairway should you play short of the bunkers crossing the fairway or risk all, then when you get to the green there are numerous undulations. After that there's no let up, the sixth has a blind shot over dunes to a large green, the seventh, don't have a putt from above the hole or you'll struggle to keep it on the green, the eighth par 5 stroke 1, the ninth, the longest 444 yards ( from the yellows) you'll meet. Ten, eleven twelve and thirteen are all excellent holes then fifteen asks you to thread your shots through the dunes wth danger lurking all around.
But don't take my word for it, just play it.
