My experience with the Callaway Big Bertha B21 irons has been a strange one.
I received these irons as a gift, and I’ve had them since early October. My first impressions of the Big Bertha B21 irons were generally positive, but the golf swing is a bit of a conundrum.
I’m not a golf swing coach, so I’m not going to be able to give you the answer to that conundrum. However, I am going to offer some insights as to how I’ve been able to swing these irons, and what I’ve learned from that.
Callaway Big Bertha B21 Irons: Design and Performance
According to the appearances, there are a lot of similarities here between the Mavrik Max iron and the Mavrik Max driver.
If you’re looking for a chunky iron with a thick top edge and lots of offsets, you’ll love the Big Bertha B21.
The Mavrik Max iron is lighter and more satiny than this iron and has a shallower face, so it appears less lofted than it really is. Apart from that, the shapes and address profiles are very similar.
On the Foresight Sports GCQuad launch monitor, we tested the 29° B21 7-iron against the 30° Mavrik Max 7-iron with Titleist Pro V1x balls.
Due to the stronger loft of the B21, it did launch a fraction lower and produced a fraction more ball speed. In both irons, the average carry was 184 yards for the B21 and 185 yards for the Mavrik Max around the 5,200-rpm mark.
The two irons appear to offer very similar performance, which raises the question of what purpose the B21 iron serves in the range.
There was a noticeable difference in the feel of these clubs. There were some minor differences between the Mavrik Max and the B21, but they were not glaring. The B21 felt a little more solid and had a slightly quieter sound, although no less explosive.
WHY YOU SHOULD BUY
- Easily gets the ball up on a strong, towering trajectory that is geared towards drawing the ball in.
- Performs consistently across a variety of strike locations.
THINGS TO AVOID
- The Mavrik Max iron has some crossover with the less expensive Mavrik Max iron.
Golfers with high handicaps who struggle with launch and strike will benefit from the Big Bertha B21 iron. There is a lot of technology to assist in getting the ball up faster, and the feel of the ball off the face is also pleasing.
