The Heater, TaylorMade® Burner Plus™ style, irons feature a deep cut cavity to move the center of gravity low and farther behind the face to optimize the clubhead's perimeter weighting producing a very forgiving and playable golf club.  The wide and beveled multi-functional sole design creates an extremely high MOI and an ease of play out of all lies with maximum forgiveness.  This is a great golf club head for mid to low handicap golfers looking for a traditional looking club with enhanced workability and forgiveness.
