The other day I was cleaning out my closet and found a dozen brand new in the box Titleist Professional 100's. Does anyone know the shelf life on these gems. Are they still fit to play with or should they go in my Titleist Shag Bag. I know golf ball technology has come a long way. As a kid I grew up playing Titleist "Club Specials". I am dating myself now. Oh well. Love all the guys and gals at Titleist. Thanks for all the hard work in making the game I love so enjoyable for all skill levels.
