More often than not, one set of wholesale golf clubs is designed with some pretty glaring selling points, including the advanced technologies, the distinctive appearance and the practical functions. Therein, the technology is playing an important role in the whole process of getting a ideal result. In this case, the designers pay much attention on the technology, such as the engineers in Callaway. They have created the outstanding Callaway X-22 Irons that are largely due to this part.
So I'd like to review the wholesale Callaway X-22 Irons mainly from the technology side. The game-improvement irons are built from 17-4 stainless steel for softness and durability and employed something called "Precision Notch Weighting," more weight positioning closer to the perimeter which increases the moment-of-inertia (MOI) for more forgiveness and increased stability while at the same time keeping the center of gravity at an optimal position for that "ideal" trajectory as well as providing added feel. By maximizing perimeter weighting, these irons boast an MOI that's 10 percent higher than their predecessors. The ideal CG position has been preserved, generating optimal ball-flight trajectories.
Besides, the X-22 irons is some fancy technology that you've come to expect from Callaway Golf such as VHT, which is the variable face technology that allows more weighting on the perimeter of the club for more forgiveness, S2H2 which allows for weight to be removed from the hosel to be used elsewhere, and Modified Tru-Bore, which allows the shaft tip to extend through the hosel and clubhead to the sole of the iron and improves feel and control by moving the tip of the shaft closer to the center of the clubface.
Callaway also refined the 360-degree undercut channel to place more weight low down in the head. The result, I discovered, is a consistently higher ball flight on those shots that have traditionally been intimidating with a tendency for a weak slice for the average player. Toss in the 360-Degree undercut channel which moves the center-of-gravity lower and farther back in the clubhead and you have a large sweetspot, which for those of us who's swings don't always repeat, is a very good thing.
