Why better players prefer one-piece irons over springy faces
The instructor explains that better players gravitate toward one-piece irons rather than ones with a springy face. Hitting this springy-faced iron, two well-struck shots carried 227 and 244 yards, and he notes a 1.2 mph swing-speed difference produced about 17 yards of carry difference. He frames that added distance variance as the reason stronger players lean toward one-piece designs.
