Best Driver I have ever purchased hands down. Thank you Titleist for making far superior products.

Mike,  great addition.. would it be possible to do a similar thing for swingweight at least for the stock shafts 

 An example of what I had in mind is  for each stock shaft

on axis length 44  44.5  45  45.5   46    second axis swingweight  D4 D3 D2 D1 D0 

Entry   screw in weight in grams to achieve each weight or N/A ( Not achievable)

This enables one to quickly set up a driver off the fitting cart to match a players existing driver swingweight as a start point without the need for a swing weight scale.  The player can then tweak the swingweight from this starting point to optimise feel for the particular shaft knownig what sort of change he is making.

This won't matter much to some but will be very important to others looking to buy the product.

Regards Chris

Thanks, that answers some questions for me.

Mike, I am wondering what the reason for leaving the face angle column on the right of the chart off all of the retail/consumer visible performance charts is? 

Also as to chris for the swing weight chart the problem with that is swing weight is not just adjusted by the SFT weight in the bottom of the club, Titleist also uses a rat glue injection in the heads (they have done this with all the clubs in the past as well) to swing weight the heads. Not all of the heads come out exactly the same weight so to be able to have all of the retail in store clubs with the red 7gram weight they must use this injection method in the head to swing weight them all out. There is usually a tolerance of about +/- 1 point as well, so not every 910 driver with the same shaft will swing weight out exactly the same. Also changing grips as well as length and the number of wraps of tape under the grip can change swing weight as well.

As a rule of thumb for every 1/2" you shorten the club you will lose 3 swing weight points. And for every 4 grams of grip weight you subtract from the club you will gain 1 point. And for every 2 grams of weight you add to the head of the club you will gain 1 point. 

So if you want to cut your driver down 1/2" and retain the same swing weight you must add 6 grams to the head. Where if you have the red 7 gram weight in the head already the 12 gram weight will still bring you out half a point short of where it was. 

Hope I didn't confuse you too much

Matthew  thanks I'm aware of the affect of shortening  grip size etc.

What interests me is the rat glue . If thats the case what is the calibration point on swingweight for the D2 heads on the fitting carts?

D3 with the  Kai'li ? give or take shaft and grip tollerances or are the fitting cart Kai'li shafts spot on?

I  tried the  'ilima 61Reg and Kali 61 Reg. The shafts on the fitting cart are standard length  with a standard size grip. The weight fitted in the head was red 7 gram,

I been told thats D 3 with the Kai'li. There is nothing in the book with the  cart about any of this rat glue adjustment. or specifying swingweight with an order.

In terms of weight tollerance of the head I would expect not more than  plus or minus 2 grams. I did a little excercise since the fitting and weighed the weight and the weights in the weight kit . The weight kit weights are spot on  but the weight in the cart head although marked 7 gram weighed just over 5 gram. I did wonder why.    So in this particular case the head was on the heavy side?  So  do they actually rat glue them all to the heavy side of the weight tollerance to achieve uniform swingweight? If they do I'm suprised by what I saw with the particular SFT weight. which appeared to have been lightened.

I found for me the club played a dream with ilima shaft  and 5 gram in this particular head In effect allowing for the difference in shaft weight  I reckon D1  ( ignoring any tollerence difference for glue tape and grip weight) The shop has the  cart but because they don't build clubs no swingweight scale so I made the best judgement I could to specify the SFT weight.

Hopefully I'm ok from what your saying   as rat glue would be added to bring up the head weight to either the  the exact spec or the upper tollerance limit whichever is the norm.  If the exact head weight spec the club will play say D0 and not D1. Thats fine as if it has lost a little feel I can get that back by adding a gram or two of weight into the drilled out 5 gram weight. If as you say its rat glue  in all cases it has to be to the upper weight limit in which case the club will be right on spec as I wanted. If its off a further point from grip glue and shaft tollerances I'll only need to put a lighter SFT weight in  if It feels a tad heavy. other wise if its off on the light side I'll be able to add a bit more weight back into the drilled out SFT to take care of that also.

So now you probably see why I've been trying to determine the swingweight spec for the 'ilima 61 Reg with the various weights ( not realising anything about rat glue).

The real answer I'm  realising is the the guys with the fitting carts all really do need to invest in a swingweight scale so that the chosen  setup can be measured and swingweight replicated in the actual club build.
