Big Bertha Fusion Irons The flagship iron of Callaway Golf is a uniquely designed iron which incorporates a new "TPU Sensert" to reduce vibration and hollow sounds and replace that with a crisp sound and responsive feel. The face of the club is made from a lightweight titanium which is 22% lighter than a standard steel face, meaning you can reposition the weight around the perimeter of the club, providing you with unmatched forgiveness anywhere off the face. As well as giving great feel and forgiveness, the Fusion iron is a highly polished finish and traditional head shape, making this an iron for all levels of golfer.
I play golf every weekend and spend 2 weeks in the summer in Spain on a golf holiday. I only use Callaway golf clubs, Callaway irons are really good, especially the Callaway Big Bertha range. Due to the large face on the Big Bertha I don't slice any where near as many shots as I used to.
