backinit With all the shaft spinning and flo'ing that I've read about (and done myself) on the "old site", how do you address installing new shafts on adjustable drivers? I am starting to lean towards the snake oil camp. I mean you can install the shaft in the adapter at neutral setting at flo, but then discover that maybe that setting isn't really the best for you and you need to make an adjustment.

I have wondered for years about how OEM adjustable drivers off the rack might have an issue with spines, flo et al.

It is all about the shaft. Get a shaft with little or no spines and alignment changes are not an issue. I have a Taylormade M2 that I installed a UST Mamiya ATTAS 5 International Series 1000 and it is sweet. I ran it through my NF2 and spines are negligible which means flex is consistent regardless or orientation in the head. I did buy the head only so I can't comment on the stock TM shaft.

I am not saying that all OEM adjustable drivers might have an issue with adjustments but shafts with large spines will vary in flex with different orientations in heads. Hopefully the OEM companies have taken this into consideration with the adjustable head drivers. Perhaps someone who has pulled a shaft on one of these could comment.

      sdandrea1 The other thing that causes my doubt is the number of quality shots and good rounds I have had with pure junk in my bag.

      But, we've never read about any under Par rounds here. So, you're still making a lot of bad shots. Even when you shoot a 75.

      Spineing/not spineing, bad swings/good swings, perfect strikes/mishits, good weather/bad weather......any little thing can contribute to a good round or a so-so round. I'd leave nothing to chance, as Chad says.

      There are probably only a handful of Pros that will say if their shafts have been spined/FLOed. They also are probably the only ones that do know if they were done. Their clubmakers would be the ones to be asked; and if I were one of them, their shafts definitely would all be aligned exactly the same. Whether I believed in it or not! If there is even the remotest of possibilities of it helping, and costs nothing, it should be done, imo.

          Few here knew of this. All who read this now know, and should realize why we spine/FLO.

            I completely agree that there is no reason NOT to do it. I'm just not convinced that I am consistent enough to benefit from it. If I had the equipment, I might do it just to learn how.

            BTW, I shot a 68 (3 under) last year in a casual round with a buddy, playing the ball down, USGA rules. It was mostly due to an excellent driving, chipping and beyond-my-wildest-dreams putting day. I had a stock set of Adams graphite shafted hybrid irons in the bag. I have had a LOT of low rounds with old Eye 2 irons in my bag 😉

                Spuzz that's because most people will believe anything you tell them even if it doesn't make sense.

                  Par4QC "Bad" is subjective. Bottom line is, we all miss all but 18 times each round.

                      puttnfool No way! How could you possibly do that without aligning the shafts?

                      I made a bunch of putts that nobody should have made. 😀

                          Have you ever considered what it is that makes those Eye2 irons play so nice? Not just for you, but for everyone that makes the statement of such? You ever try the ZZ lite shafts in other(non PING) heads?

                              They perform well because of the synergy resulting from the shaft characteristics coupled with the head design. You still can hit lousy shots with them. Are you saying that ZZ Lite shafts are Flo'd/aligned? Is that even possible with a steel shaft?

                                  puttnfool Never hit a tee shot OB, eh?
                                  Hit every Par 3?

                                  There's always the remote chance of zero good shots per round!

                                      sdandrea1 Flo'd/aligned? Is that even possible with a steel shaft?

                                      Absolutely.

                                      My point about the ZZ lites....they are stiff tipped, high bend shafts. Ever play other shafts with that profile and do well with them? 😉

                                          Rickochet I know what theories you believe in. Just as I do with "flat earthers" I dismiss your theories because of the level of hogwash.

                                            Rickochet Spine alignment in drivers is much more critical than alignment in irons.

                                            Rick - is this because the driver shaft has the most "flex-movement" in the swing? Do stiffer shafts have less risk for this topic? Do steel shafts have spines? I am curious.

                                                Par4QC Negative, ghost rider. If you're playing by the rules and holing out, then you hit 18 shots per round. No more, no less.

                                                    puttnfool I'll admit my lack of knowledge here in the adjustable driver realm. When you adjust the loft/face angle, does the logo on the shaft change orientation?

                                                    I don't participate much anymore, but I can't help myself. You don't know the answer to that question but you feel you know enough to declare spine aligning as snake oil?

                                                        Ahhh, I see. No - never. That bend profile would not work for me another head. Do you think PING aligned those in mass production?

                                                            Now Steve, that statement just makes no sense. I'm giving you a reason to HO. You need a set of heads with similar lofts as the Eye 2 heads, and another set of ZZ lite shafts, no?😜

                                                                Par4QC You need a set of heads with similar lofts as the Eye 2 heads, and another set of ZZ lite shafts, no

                                                                That sounds like another set of Eye 2 irons. 😙
