Abstract
The present invention provides a golf club set comprising differently numbered wood clubs and differently numbered iron clubs. The shaft of each club have reverse deflection which is defined as displacement of a standard shaft point when a predetermined load is applied to the shaft a predetermined distance from the shaft head end with the head end fixed. The reverse deflection of the wood club shafts decreases proportionally as the wood club number increases. The reverse deflection of the iron club shafts decreases progressively as the iron club number increases, and further retains proportionality relative to the proportionally decreasing reverse deflection of the wood club shafts.
