The raised steel mass area of the Houdini Sole at the rear of the clubhead reduces the amount of sole area to reduce drag and turf interaction.
The Houdini Sole is instrumental in significantly altering the CG placement of the E521 hybrid. The CG is 7% lower and 30% further back than the previous HL4 Hybrid, making E521 the highest launching and easiest to hit hybrid Tour Edge has produced. It also helped raise the MOI of the clubhead by 9%.
HEEL SOLE WEIGHT
The strategically placed heel draw-bias weighting of the E Series offset designs are engineered to help golfers avoid the right side of the course and to increase launch conditions.
SLICE-FIGHTING OFFSET DESIGN
Slice fighting technology in the offset E521 hybrid allows the face to square up at impact for straighter ball flight.
SHALLOW FACE DESIGN
The super-shallow Cup Face design in the Hot Launch E521 Hybrid produces higher launch angles and extreme ease of launch. The face was designed with a 5% shallower face than the previous Hot Launch iteration.
