Hi Joel -

The 910 wrench works with all the metals.  We recommend that you visit a local Titleist fitting partner to help you identify which shaft is best suited for your swing.  If you would like assistance finding a Titleist fitting partner just provide us your zip code and we'll be happy to recommend a location.

There are 2 settings which will produce less loft and help promote a right to left ball flight (C2 & D2).   C2 is .75 degree less loft and .75 degrees upright.  The more upright you go the more right to left movement you are likely to see, so D2 at .75 degree less loft and 1.5 degrees upright will likely produce more draw bias.

Hey Joel,

To answer your question, "What does torque mean?: the simple answer is torque is the turning force required to move an object in a circular motion. Initially when you screw a screw in a block of wood it requires little force or torque but as you when you get to the end of the threads, you naturally apply more torque to insure the screw is in tight. This principle holds true when joining the Titlest supplied screw to the head sleeve of your driver. Torque is an important measurement in a lot of industrial applications. As an example, the bolts that hold a car engine together are torqued to a certain force or the engine might come apart. The reason the bolts are not torqued with an even greater force than required is that the bolt itself may be destroyed or weakened. One could actually tear the head off of the bolt if to much torque was applied. As a further explanation, the exact moment the bolt head contacts the engine block, you could stop the turning but there would be a good chance that the bolt would vibrate off. Mechanical engineers determine how much more turning force is required to insure the bolt "sticks" and does not come loose under normal conditions while at the same time insuring the bolt is not damaged. As a practicle example, a special "torque" wrench is used by garage mechanics. It has a physical needle gauge, that shows him how much force he is applying (that force is equal to weight as a measure of pounds of weight applied on the wrench handle). Of course if a mechanic did not own a torque wrench or was in a hurry, he might tighten a bolt with a regular wrench too tight or too loose when he applied his force to the wrench handle by what felt "about right" to him. Usually they would do it too much as in the case of my strong dad, ha. This is why Titleist has supplied us with a special torque wrench. It is "special" in that the design does not require a needle gauge. Once the required turning force is applied, the inner workings of the wrench insure that the joining components of the the wrench "slip" (that's the click sound) once the correct amount of force is applied. This insures that neither the screw head, screw threads or hosel shaft threads are damaged. If this wrench was not supplied, some of us would not tighten the screw enough which might result in the head coming off unexpectedly or some might damage the screw, unknowingly, with to much force; also allowing the driver head to fly off at an inopportune time.

Word of caution, if you read the back page of the Titleist wrench booklet carefully, you will see the warning to ensure that all connections are inspected frequently to ensure they are tight. I plan to not only visually inspect my hosel / shaft connection before play but also, depending on how much I play, too once and a while back off the hosel screw and re-tighten with my torque wrench.

Finally Joel, I am enjoying my 60 weight Aldila RIP shaft with my 910.  I would recommend a 60 weight shaft if your swing speed is less that 100 but of course the shaft type and weight are highly personal preferences.

Thank you very much for the information!!  Have a great season....

Hey Joel,

After my post concerning your question about torque, I realized that you could have been referring to golf shaft torque and not the torque wrench provided by Titileist. I will leave it to an expert to fully answer questions about golf shaft torque but I will say it is the same principle of turning force or turning moment. Some composite shafts will turn more easily than others when striking the golf ball just as a regular shaft will bend more than a stiff shaft. Obviously, steel shafted irons have less torque and that is one reason that pros play them in their irons as they offer less dispersion from the strike than a graphite shaft would although with the newer composites and manufacturing processes the differences is a lot less than you might think.
