How does shaft flex affect ball flight?

Too flexible shaft: excessive kick creates high launch and right dispersion (for right-handed golfers). Too stiff shaft: low launch, left dispersion. Matched flex maximizes energy transfer and tightens dispersion pattern.

What is the most important shaft fitting parameter?

Driver swing speed is the primary parameter. However, tempo (fast vs slow transition) also matters: a fast-tempo golfer often needs stiffer than speed suggests; a smooth-tempo golfer may use softer. Dynamic fitting on a launch monitor is ideal.
