My old Callaway Warbird 5 Wood, good shots or bad, I knew when playing it when I was at the top of my form or way off. And sometimes hitting balls with it at the range would get my swing groove back in no time.
Ya, being an old timer myself I had to pick a personal favorite for my number 2 that still impresses with his game. By the way I played a course he had designed a few times when I lived in Northern Va.: Westfields. IMHO one of the better ones.
