Callaway developed these irons so there were no sacrifices in distance, feel or forgiveness. The RAZR X irons feature a low, deep centre of gravity that delivers high launch combined with long shots off the thin face. In fact, by moving 30g of weight in the back cavity, Callaway have been able to position the CG 12 percent lower and 15 percent deeper than before. Callaway have lots of irons, but these are probably the best for the game-improver. www.callawaygolf.com or 0800 096 4591
