Abstract

A method is disclosed for effectively guiding golfers and/or their fitting professionals toward the selection of a particular wood-type golf club that is optimally matched or fitted to each golfer'"'"'s particular swing characteristics, the selection being made from a set of golf clubs having at least three different head sizes and being made based on one or more swing characteristics for the golfer.

a) determining a value for at least a first swing characteristic for the golfer; and

b) selecting an optimal golf club from the set of golf clubs, such selection being based on the value of at least the first swing characteristic.

2. A method of selecting a wood-type golf club for a golfer from a plurality of golf clubs having at least three different head sizes, each having a head volume of at least 300 cc, comprising:

a) selecting a first golf club having a first head size, a first loft angle, and a first shaft flex;

b) swinging the first golf club more than one time to obtain a value representing at least a first swing characteristic;

c) selecting a second golf club based upon the value representing at least the first swing characteristic, the second golf club having a second head size, a second loft angle, and a second shaft flex;

d) swinging the second golf club to hit a plurality of golf balls and obtain a value representing a second swing characteristic;

e) swinging a third golf club to hit a plurality of additional golf balls and obtain a value representing a third swing characteristic, to validate the selection of the second golf club, the third golf club having a third head size, a third loft angle, and a third shaft flex; and

f) selecting an optimal golf club from the plurality of golf clubs, the optimal golf club having a first, second or third head size, a first, second or third loft angle, and a first, second or third shaft flex.

3. The method of claim 9, wherein the second and third swing characteristics are the same.

4. The method of claim 2, wherein the value for at least the first swing characteristic is an average swing speed of the golfer.

5. The method of claim 4, wherein the value of the second characteristic is a ball launch angle or a spin rate.

6. The method of claim 5, wherein a relationship between the average swing speed, optimal ball launch angle, and spin rate is predetermined, such that steps c) and e) comprise referring to a chart.

7. The method of claim 2, wherein a relationship between the value representing at least the first swing characteristic and the value representing the second swing characteristic is predetermined, such that step c) comprises referring to a chart.

8. The method of claim 7, wherein the plurality of golf clubs are numbered sequentially, for selection of the second and third golf clubs, the numbered clubs being referenced by the chart.

9. The method of claim 2, and further comprising swinging a fourth golf club having a fourth head size, a fourth loft angle, and a fourth shaft flex, to validate the selection of the second golf club, the optimal golf club comprising an optimal head size corresponding to the first, second, third or fourth head size, an optimal loft angle corresponding to the first, second, third or fourth loft angle, and an optimal shaft flex corresponding to the first, second, third or fourth shaft flex.

10. The method of claim 9, and further comprising swinging a fifth golf club having a fifth head size, a fifth loft angle, and a fifth shaft flex, to validate the selection of the second golf club, the optimal golf club comprising an optimal head size corresponding to the first, second, third, fourth or fifth head size, an optimal loft angle corresponding to the first, second, third, fourth or fifth loft angle, and an optimal shaft flex corresponding to the first, second, third, fourth or fifth shaft flex.

11. The method of claim 2, and further comprising applying face tape to the first golf club and using information from a dispersion pattern that is produced on the face tape after the first golf club is swung a plurality of times, to aid in selecting the optimal golf club.

12. The method of claim 2, wherein the at least three different head sizes vary from each other by at least 20 cc.

14. The method of claim 13, and further comprising providing a cart to hold the plurality of golf clubs.

15. The method of claim 13, wherein the substantially similar engravings comprise a scoreline pattern on the face of the head of each of the plurality of golf clubs.

16. The method of claim 13, wherein the substantially similar engravings comprise a brand marking or logo on the head of each of the plurality of golf clubs.

17. The method of claim 13, wherein the heads of the plurality of golf clubs have a similar finish.

18. The method of claim 13, wherein the heads of the plurality of golf clubs have a substantially common construction.

19. The method of claim 18, wherein the substantially common construction comprises a cast body and a face plate welded to a front opening of the cast body.

20. The method of claim 18, wherein the substantially common construction comprises a common material for at least a body portion of each club head.

21. The method of claim 13, wherein the different head styles comprise at least two different address planforms, the planforms including a difference in size or shape or both.

22. The method of claim 13, wherein the different head styles further comprise at least two different ratios of face height to head depth.

23. The method of claim 13, wherein the different head styles further comprise at least two different face aspect ratios.

24. The method of claim 13, wherein the different head styles further comprise at least two different weight pads, the weight pads differing in size or location or both.

26. The method of claim 25, wherein the substantially similar engravings comprise a scoreline pattern on the face of the head of each of the plurality of golf clubs.

27. The method of claim 25, wherein the substantially similar engravings comprise a brand and marking or logo on the head of each of the plurality of golf clubs.

28. The method of claim 25, wherein the heads of the plurality of golf clubs have a similar finish.

29. The method of claim 25, wherein the heads of the plurality of golf clubs have a substantially common construction.
