As of late, I have noticed what tinkering with your bag can do for your game and feel that that club I've added to the bag has become my secret weapon to taking on courses with almost the greatest of ease. I love my 917 F3 and it's trusty and have even used it more than the driver. However, the secret weapon replaced my 915 Hd Hybrid and I feel I can hit it from anywhere and any shot I want. The 716 T-MB 3 iron is one bad-to-the-bone club! I've carried a 3 iron before but this club is a game changer. What's your secret weapon?
