In 1974, I got a set of old Tommy Armour irons with no chrome on them. These dull-gray clubs had a soft feel to them that was just exquisite. The irons were 25 years old, but after I sawed down the hosels and added some lead tape here and there, they were like magic. I got on the hottest streak of my career. I won eight times on the PGA Tour in 1974, knocking down flags every week. The following year I signed an equipment contract and had to put the Tommy Armours in the garage. Big mistake. No matter what I did, I couldn't make the new clubs perform like the old ones. If you've got a set of irons you really like, think twice before switching to a new set. There are a lot of great new irons out there, and you might fall in love with how well you hit them on demo day. But when you get on the course and face funny lies and try to hit shots, like a high draw or a low fade, you might find they're completely different.
