Golf club set
Set 2 according to the present invention includes m or more wood type golf clubs (wherein, m is an integer of no less than 2) having a loft angle of greater than 20 degrees. Provided that the face progression b2 of these m clubs is defined as from b2 (1) to b2 (m) following the ascending order of the loft angle of the club from the smallest value, this set 2 satisfies the relationships of:b2 (1) ≧b2 (2) ≧ . . . ≧b2 (m); and b2 (1) >b2 (m).Preferably, in all clubs having a loft angle of greater than 20 degrees, the ratio (a2/b2) of the loft angle a2 (degree) to the face progression (mm) is 0.7 or greater and 2.0 or less in this set 2. This set 2 is superior in ease to address. According to this set 2, the trajectory suited for each numerical designation can be achieved.
