This is an absolutely must-have if you travel with a soft travel bag. I travel extensively with my clubs, and this is cheap insurance. Before purchasing a Stiff Arm 5 years ago, I'd lost two drivers, once as I watched a baggage handler drop my clubs from the airplane cargo door head first. Since I started using the it, though, I've not had a single problem. I'm replacing the original Stiff Arm because it's given it's life protecting my driver so many times!
Spend $27, save $400 for a driver. Not a difficult decision.
Pros: Quality, Durability, Easy to Use, Good Value, Features
