Nicklaus Golf Polarity TR1 Iron: Hi, I’m Clay Long, and I serve as chief designer for Nicklaus Golf Equipment Company. Today, we’re here to look at the Polarity TR1 Iron for 2009. The TR1 iron exhibits Polarity extreme weighting technology, as do all the Polarity clubs in the Polarity collection. The TR1 iron, however, has been designed for the little better player or the more accomplished player. It exhibits a little thinner sole, a shorter blade, a thinner top line, and quite a bit less offset than the Polarity iron. All of these factors are slanted toward the more accomplished player, middle handicap player, who would like to have those playing characteristics in his club along with the added forgiveness that comes with the Polarity technology. An extremely good looking club behind the golf ball, as would be required by Jack Nicklaus himself. It exhibits a urethane insert in the back as well to cushion impact and give the club exceedingly solid feel, all in a quite forgiving iron. And that’s the Polarity TR1 Iron from Nicklaus Golf Equipment Company.
