Taylor Made must be doing something right, because Mark O'Meara and Lee Janzen were using the new FireSole driver when the 1999 PGA Tour started. If the woods are distinctive, the irons are positively radical. The long irons are different from the mid irons, which are different from the short irons. FireSole long irons are made of titanium with tungsten sole weighting. Mid irons are made of stainless steel with tungsten heel and toe weighting.
Short irons are stainless steel with no additional weighting.
The idea is to help get the ball airborne with the long irons and keep it down with the short irons. Taylor Made engineers didn't stop there. They created a hybrid line of utility woods called the Rescue, with a small titanium head and 100 grams of tungsten bolted to the sole. As a result, the Rescue looks like a compact Raylor, the line of railed fairway woods from Taylor Made. It also resembles the once-popular Exculpator woods from Tommy Armour.
