Our newest golf improvement products, the XD and the XDS are antislice golf balls designed for the recreational golfer who struggles with hooks and slices off the tee, but perhaps hits a fair number of straight shots as well, or whose hooks or slices are not particularly severe. For this player, we’ve designed the XD and XDS to correct up to 50% of hooks and slices, so if your slice typically goes 60 feet to the right with a normal ball, this ball will only slice about 30 feet. As with our Ultimate Straight balls, both the XD and XDS each have the exact same dimple patterns so both are equally “self correcting”. The XD is a 2-piece construction, while the XDS is a 3-piece construction designed for higher spin into the green off of short irons. Because these balls were designed to be less corrective than our Ultimate Straight, we were able to raise aerodynamic lift just a bit, so these balls will fly higher in general, and ball flight should be fairly typical with your standard driver. The resulting ball flight will result in a higher trajectory and longer carry distances than our Ultimate Straight golf balls – hence the designation “XD” for Extra Distance (relative to our Ultimate Straight).
