- It is important to note there are many similarities between the two sets of irons. Much of the technology involved is similar and executed with the same aim because both sets of irons are well down the X series line. Both sets are considered "game improvement" irons, geared toward greater forgiveness and stability rather than feel (unlike irons considered "blades"). Both sets have an additional "tour" version with a more precision-based dynamic shape. Weighted notches toward the perimeter of the club redistributes the weight and allows for a more stable and forgiving club. The design of both sets also includes an undercut channel, intended to move the center of gravity lower and back in the club, resulting in a larger hitting area.
Difference in Performance of the X22
- Produced two years after the X20, X22 irons have the benefit of being more refined and advanced. The top line and sole of the club are slightly thinner than the X20 version, as Callaway was seeking a tour-inspired design and head shape. The club also has a 360-degree undercut channel, a more refined version of the channel seen earlier on the X20. The club is also touted as adding a few yards of distance to your shots compared to previous models. Because it has a slightly lowered center of gravity, the clubs tend to induce a higher ball trajectory.
Difference in Performance of the X20
- Because of its design as a "game improvement" iron, the X20 has a slightly larger club head and top line than its younger brother. Its 180-degree undercut channel is different than the X22, and results in an overall different look and feel. Though reported to travel a few yards shorter, the club has a lower and more controlled trajectory.
- The performance of the X20 set is not hugely different than the X22, and yet it comes at a much lower price. Though the X22 is two years more refined, the differences themselves are small and subtle, and for many people may not represent a huge difference in play.
