Persimmon Back In the Bag!
This is from an e-mail I received today from Frank Thomas, formerly of the USGA and an authority on golf equipment. He sends out Questions and Answers that you can go to his website and see archived. This one relates to Persimmon. Mr. Thomas, who we deeply respect and was a friend of Louisville Golf founder Elmore Just, has also, in the past, participated in some of the marketing hype that has golf under its spell currently (as you can reference on the Persimmon bLog here). In this exchange he seems to give Persimmon fairer treatment, and for that we are grateful.
Persimmon Back In the Bag!
Frank,
I went to the range today for lunch and put an old Powerbilt Citation 5-wood in my bag that I found in my garage to take to the range for fun. I haven’t hit a persimmon wood for at least 15 years and was AMAZED at how high and soft it landed on the green 220 yards away. I then took out my Callaway hybrid and hit it just as far and pretty straight but nowhere near as high. Also, I noticed when I hit the persimmon closer to the toe it would draw in and hit a couple on the heel and faded. I felt like I couldn’t miss the target! It landed so softly I was stunned. Am I the only one who is now thinking I should put my persimmon 5-wood in my bag as opposed to these high tech hybrids?
Best regards,
Michael

Michael,
It should not be surprising that your wooden 5-wood will perform very well and certainly after such a period of purgatory in the closet. It has now learned its lesson and obviously doesn’t like a dark place away from the course. There are other reasons for good performance and this has something to do with your fresh swing and obvious affection for this well-crafted old friend and warm instrument.
Let’s examine the wooden 5-wood from a technical point of view - which may not be half as important as your attitude and good swing motion. The COR (Coefficient of Restitution) is probably very close to that of your hybrid so the ball will come off the club at about the same speed. Because the c.g. (center of gravity) of your 5-wood is most likely farther back from the face than the hybrid the face will present more dynamic loft to the ball at impact. This will send the ball on a higher trajectory, assuming a similar shaft flex. A more flexible, longer shaft will further increase this dynamic loft. The longer shaft - which I suspect is the case but you need to check this out - will allow you to generate a little more head velocity giving you increased ball speed even though the COR is the same.
The down side - for the 5- wood - is that the Hybrid, which probably has a higher MOI (Moment of Inertia) about its vertical axis and thus will be more forgiving i.e. not twist as much on off centered impacts. It is for this reason that the “Gear Effect” using your wooden 5-wood, is more pronounced when the impact point is on the toe or heel as you describe.
Have fun with your old friend and don’t let it or any other good friend spend long periods of time in a place it doesn’t enjoy. Some will sulk and never perform properly again. I hope this has helped give you a better insight into the social and technical behavior of your old friend.

I have a few points for pondering. Mr. Thomas alludes to the social behavior of the experience Michael had with his 5-wood, something we recognize as the spirit of the game which we promote. Michael exemplifies thousands of golfers who recharge their love of the game with this type of experiment, either by purchasing a club from us or resurrecting old glory from their closet. “The truth is what works,” whether arrived at socially or technically. What is interesting about Persimmon fairway woods is that they have NEVER been tested against fairway metals or metal hybrids. Mr. Thomas says a metal hybrid “probably” has more MOI than a Persimmon fairway wood, but one has never been tested for this or distance. I am willing to bet the stake of our company on the fact that a Persimmon fairway wood will perform overall just as well as a metal, and the experience Michael had testifies to that end.
