is surely at play here. The G440 4-iron, a game-improvement design built for players who want forgiveness and don’t mind playing a larger profile, was actu- ally the biggest carry beneficiary at 85 mph with more than a five-yard boost from a steeper blow. That’s a meaning- ful number for moderate-speed players, driven by spin dropping more than 400 rpm without much loss of launch angle. For slower swingers who carry a game- improvement iron, a slightly more de- scending strike is worth pursuing. Clearly, this topic is more nuanced than a single swing tip. The 3-wood wants to be swept. The 5- and 9-woods – and less so the 7-wood – reward a de- scending blow. The 5-hybrid benefits from getting steeper; the 3-hybrid not so much. The G440 4-iron at moderate speed responds to a little steepness, but the utility iron is just as good at neutral. The slot between the driver and irons requires some thinking. Set makeup is critical, and now our data confirms that attack angle can affect how each club performs. Choose – and swing – wisely.
yards at both speeds, with spin drop- ping meaningfully at 85 mph but hold- ing relatively flat at 95 mph. It benefits from the steeper angle, just less dramat- ically than the 9- or 5-wood. The 3-wood is the outlier, and it’s an important one. Unlike its higher-lofted stablemates, the 3-wood actually lost carry with a steeper attack angle – down two yards at 95 mph and six yards at 85 mph. At 15 degrees, this club is already running lower spin numbers (3 928 rpm at 95 mph with a neutral delivery) and a flatter, more efficient ball flight. There’s simply less high spin to correct. Forc- ing a descending blow here drops the launch angle without a proportional spin benefit, and carry suffers as a re- sult. The advice to sweep is actually good for the 3-wood. Interestingly, the hybrids were split. The 5-hybrid gained about six yards of carry at 95 mph with the steeper angle of attack, with spin dropping more than 400 rpm – a meaningful response that mirrors what the higher-lofted fairway woods showed. The 3-hybrid was much
less affected: a marginal carry gain at 95 mph but a slight loss at 85 mph. This tracks with what we know about hybrids: Because of the geometry of the head, they tend to spin less than fairway woods of similar loft. It makes sense that getting steeper helped the higher-lofted one more, given that its spin numbers started higher. With the irons, the story shifts again. The iDi 3 utility iron was largely indif- ferent to attack angle – barely a yard of carry gain at 95 mph and a slight loss at 85 mph, even as spin dropped notably at slower speeds. Like with the lower- lofted hybrid, the weighting in the head When we moved to a descending blow [with the 9-wood], the spin rate dropped . . . and carry distance jumped about seven yards.
