【EASY TO HIT 】More loft helps get the ball airborne more easily. Face depth/design influences how easily you can compress the ball and get good launch without needing extreme swing speed.
【SOLID FEEL】 Good feedback / impact sensation. You sense a firm, responsive hit rather than something mushy, soft.
【FORGIVENESS】Reduces the penalty for off-centre hits. Even if you don't hit the sweet spot, the ball stays more on line and you don't lose as much distance.
【BIG SWEET SPOT】Maximum legal head size (~460 cc) gives more forgiving face area. Larger sweet spots mean even if you hit off the centre, the loss of performance (distance/accuracy) is less severe.
【BETTER FOR SLOWER SWING SPEED】Design the sole, crown, and weight layout to lower the center of gravity without compromising forgiveness.
