With the release of its new 588 Altitude, MT and TT irons, Cleveland Golf is giving consumers choices: They can play one of those sets in its entirety, or create bags that include clubs from any combination of the three. Some of the equipment maker’s staff professionals have gone the custom route, with Graeme McDowell and Keegan Bradley using mixes of MT (for Mid-Trajectory) and TT (for Tour Trajectory) clubs in competition, for example. And Cleveland Golf engineers expect many recreational players to do the same, as they also see other golfers confining themselves to one specific line. The options, it appears, are endless. It is highly doubtful that any touring professionals will put the 588 Altitudes into play, however, for those are pure game-improvement clubs with a lower, deeper Center of Gravity designed to launch the ball high while being easier to hit. But they could certainly appeal to mid- and high-handicappers enticed by the full-hollow construction of these sticks. Each has a forged face made to enhance ball speed and feel and comes with a bendable hosel that enables players to adjust lie as much as 2 degrees lat or 3 degrees upright. The 588 MT irons feature full-hollow construction as well, though the heads in these clubs are not as big and bulbous as those in the Altitude line, and utilize Cleveland Golf’s face-forged technology. While the blade length is constant throughout the set, the blade height increases progressively into the higher-lofted clubs. In addition, the MTs employ a multi-material insert of polymer and aluminum to dampen vibration at impact.
