Adams rewrote the book on iron-set integration five years ago with the original Idea. The third-generation Idea, called the Idea a3 Hybrid, comes with newfangled hybrid long irons (3-5), hollow middle irons (6-7) and cavity-back short irons (8-PW), for those who swing the driver 85 to 105 mph. Its calling card is a boxy, rectangular hybrid reminiscent of square drivers.
The idea is to push weight to the extreme rear heel and toe. This creates a lower center of gravity, so shots get airborne easier, and a higher moment of inertia (MOI), which means forgiveness when you don't strike it dead solid perfect.
