Here we go!
Tony-We started out using an old shaft deflection board. It allowed us to see the bend point and profile.Bruce thank you for this article. I guess the thing to me about what you write is - is there some way to actually measure tip stiffness for putter shafts, or do you just try different putter shafts and see which feels differently and "connects" with your stroke? Tony
Great,,,,,,, now I got the urge to experiment,,,, time to go look for a decent putter and start playing with grip/shaft combos,,,,,Hey TJ
1. Reduces or increases vibration frequency post impact. If you can compare apples to apples - same putter head, grip and same weight - the response we got was a softer feel from the slower vibrations. A little firmer or crisper feel from a stiffer shaft. Nike measured all of this a number of years ago, and that testing triggered some of my own. We also found that all things the same except flex, that the feedback that the softer shaft felt heavier. Remember in all these tests there was a full flex different putter to putter. We called it soft, medium and firm.
2. We did not or could not see any rotational influence from the shaft. Having said that we did not test any putts more than 25 feet. But all were steel shafts with the same nominal torque of 1.8 degrees, but none of the putts we hit would come close to applying the amount of stress used to obtain the measured rating. I suppose if you had a graphite shaft with a higher torque measurement you might see some on longer putts.
3. IT IS MY OPINION flex point will influence feel but I can't prove it ....yet.
I apologize it this is a little vague. I am working on some things that, for now, I should keep to myself. Having said that i encourage you to try some things out. Byron has tipped shafts for me in the past.
I have some putters with pencil shafts and will be looking for this. Really something I never thought of before. Would you think it might be a mental concept, as the shaft is more delicate in appearance?For most "tests" the results are only applicable to the humans performing the tests.
We have found that feedback can be predictable. For example we can predict that in comparison a player will slow his tempo with a Mills pencil shaft when compared to a similar model with a stock over the hosel shaft. Can't predict exact measurements but we see the trends pretty clearly.
I believe the putter industry has "evolved" to producing putters with too heavy of a head. The heavy heads have created a demand for heavier grips, and, or, counter balance weights at the butt of the putter shafts.Take this for what it's worth, but I've grown to love lighter putters, but also balanced putters with counterweight. For those who gave counterweight a try at normal weights, with a steel shaft and hated it, might want to try a graphite option as well, the lessened static weight could be a game-changer. I currently game a Byron Longneck DH89 at 32.75", 338g headweight, 60g Pingman, 50g counterweight, and a stiff graphite shaft that is about 45g installed. I've got a putter now that is about B-0 swingweight, at 495g total weight. The *feel* with this putter is amazing and my distance control & overall putting in general has NEVER been better. Ymmv
I agree with most of what you said, and I'll add that for me, with less weight overall and less in the head I'm more able to putt with my finger-tips and less with my palms, if that makes sense.I believe the putter industry has "evolved" to producing putters with too heavy of a head. The heavy heads have created a demand for heavier grips, and, or, counter balance weights at the butt of the putter shafts.
I think that about 15 years ago consumers started to like heavy head putters, mostly because a mishit with a 350 gram head "sounds better" (feel at impact) than a mishit with a 310 gram putter head.
