As much as you want\n$1,100 (set of eight, steel)\n\nThe Carpenter-steel face insert, which is designed to flex at impact, is welded into a forged-steel frame. The purpose is to control vibration for improved feel. There's also tungsten in the soles of the 3- through 5-iron to lower the center of gravity.\n$800\n\nThe redesigned slots in the 3- through 7-irons are three millimeters longer than those in this year's RocketBladez, and the slots become thicker near the toe and heel for improved performance on heel and toe mis-hits. The face gets as thin as 1.5 millimeters.\n$500 (seven irons)\n\nThis 431 stainless-steel cast iron has tungsten weight pads in the heel and toe of the sole for a low center of gravity. The weighted heel and toe is bridged by a cavity in the sole to enhance feel at impact and improve turf interaction by reducing its contact area.\n$700\n\nThe thin, multi-thickness face is designed to increase ball speed. A deep, undercut cavity in the 4- through 7-irons lowers and deepens the center of gravity. The set can be combined with JPX Fli-Hi hybrids, which feature the same lengths and lofts as the irons they replace.\n$600\n\nThe C100 is more compact than its predecessor (Ci11) and features a thinner face designed to yield higher ball speed. The external frame is similar in concept to the Ci11 but weighs 75 percent more for improved perimeter weighting and stability on off-center hits.\n$800\n\nThe long and middle irons have a thin face, a low center of gravity (CG) for a higher launch and a tungsten toe weight to improve off-center-hit performance. The short irons feature a slightly thicker face for a slightly higher CG and a more penetrating ball flight.
