The Rogue ST steel line consists of the game enhancement components. Hollow-body Rogue ST Max, a modern iron for long-distance players, and the strong-lofted Rogue ST Max OS, a club designed for long-distance players. There’s an OS Light version of the Renegade ST Max OS, which is lighter and has much more lift to help slower swingers get the ball up in the air, just in case. Read the article to know all about the iron used in this and if this would be ideal for you.

The deep dive: Callaway’s designers used a new face material to enhance three of the company’s core iron technologies to create the Callaway Rogue ST metal family, which includes four models for gamers of varying abilities. According to Callaway Golf’s director of iron design, Scott Manwaring, they’d “reached the limit of trying to cast face images with 17-4 stainless steel”. Using 450 metal for the face cup, on the other hand, allowed the top and bottom of a face to wrap around a portion of the peak level and sole. The new face cup can marry to the 17-4 steel body at the heart of every new set of irons. Additionally, each head is designed using artificial intelligence so that the faces aren’t just thinner. But narrower in the areas where the type of sportsman is most likely to be drawn to whatever iron category, those playing are most likely to benefit from the new face material. 

To avoid sounding clattery or tinny, thin-faced irons must be carefully designed. It is common practice to use fillers of one kind or another behind the face or even in the cavity to dampen sound, but this can reduce ball speed. On the other hand, Callaway uses a urethane compound containing millions of microscopic air spheres. A few previous irons from the company used this technology back to the third or 4th groove from its bottom surface. In the Renegade ST irons, the sixth groove extends to the end. Besides providing a comfortable grip, it covers 80-90% of the region where steel impacts occur, allowing the face to remain flexible. 

Callaway Rogue ST Pro’s irons have a shorter blade size and less offset or narrower sole, appealing to the more experienced player. As suggested by Hocknell, “It has more loft than Apex Pro, but it lacks the forgiveness of Apex.” Someone seeking a balance between those two options might be interested in this iron. 

Those that have seen a Callaway steel before can recognise the ST Max version’s shape. As Hocknell put it, “This fits the vast majority of the market.”. “The CG is half as low as Mavrik, or the lofts are substantially weaker. That improves the relevant results and the descent angle,” he explains. The hosel length progression (longer in long irons, shortened in short irons) that makes it easier to square up the long irons at impact is likely to go unnoticed, but it is no less valuable. 

ST Limit OS is slightly bigger than the Max, allowing those who frequently swipe it across multiple face areas to work with more room. Fitters and sales representatives told us that a Lite version would be a welcome addition to the line, so we created it. Not only are the Lite’s weight and swing weight lighter, but the loft is 3 degrees relatively weaker than the output Levels to focus on launching the ball.
