Anyone who played in the 90s, likely has fond memories of the x series irons. This iron is a nice homage to those clubs. The feel/sound off these clubs is a bit loud/clicky, which is taking some getting used to. But the performance is there, though I don't really see much distance gains over my current Callaway irons (Diablo forged). Ball flight is medium-high, and irons afford decent stopping power, despite the lower spin rates. Well done Callaway!
The classic Steelhead iron is back with some upgrades! The Steelhead XR iron set increases distance with Callaway’s 360 Face Cup technology. The Face Cup increases distance on shots hit in the center or off-center.
A hollow Bore-Thru hosel design in the Steelhead XR iron set moves weight from the hosel to more beneficial locations in the head. Moving the weight increases forgiveness.
The Steelhead XR iron set also has a progressive CG position. The CG position lowers as the clubs get longer, raising the launch as loft decreases. This results in more ball flight control throughout the set.
