Physics doesn't lie. Every club head has a fixed weight. The question is where you put it.
Most manufacturers concentrate weight toward the center — it looks clean, feels solid, but when you miss the sweet spot, that's when the ball drifts. Perimeter Weighting (PW) distributes mass along the outer edges. A larger effective sweet spot. Less twist on off-center hits. The ball goes where you aimed it.
