New Adjustable drivers (R9, Titleist 910 D2,D3) using old ball flight laws or not?

[Joeyvee]

So I was reading about the new Titleist 910 D2 and D3 drivers and they had a graphic that showed with adjustments a higher trajectory and more or less draw and fade. Do they attempt to create more of a draw by just closing the face more? We all know now that the position of the face at impact only dictates where the ball STARTS on its flight and not the actual path of the ball (draw or fade).
So are the drivers that say you can change the path of the ball with adjustments all full of **** or is there some way to actual make this happen using the new correct ball flight laws. I dont see how but then again I'm at work not focusing a whole lot.
I have a TM R7 and I can vouch for the trajectory changing with weights but I've never moved the weights to try and get it to draw more. More weight in the heel and less in the toe would close the face and just make it start a bit more left no?
I mean it wouldn't change the swing path so it COULDN'T change the shape no?
Am I missing something or are these club manufactures wasting millions and millions of dollars on R&D; and development for nothing. They can't be.
So what's the truth?
Titleist admits it's not a 40-50 yard left to right adjustability like TM claims in their driver. It's more of a 10 yard right to left and more focused on trajectory and lie..
So what the hell is going on?
I'm just going to get a 10.5 Ping G10 and be done with it.
With what we know now about true ball flight laws how is this even possible? How does it even make it to market? I mean trackman and those ball flight laws were figured out a year or three ago.. Not a week ago..

This is only half correct. Yes, the clubface determines the initial direction of the ball. However, the differential between the angle of the clubface and the angle of the swingpath are what create your draw and fade.

In context with your question, a draw or fade bias setting (closed or open face) will affect the draw/fade of a shot, because it will influence the relationship between the clubface and swingpath at impact.

Aim right with a draw bias club head and the ball will most likely draw, assuming your swing mostly on plane. I bought a Callaway I-mix FT-i draw a few months ago and wow, I can hit big sweeping draws, I could not do this with a neutral driver before, definitely not with a Tour setup. It's now almost impossible for me to hit a big fade with this club, but I could with my Hibore Tour (1-2* open). I few years ago I couldn't play a draw to save my life, natural shot was a big fade; I tried the FT-i in 2006 and was completely amazed at how the ball started to fade but then straightened out midway thought the ball flight...very, very cool. Now that I have the I-mix set up, I can adjust my club for the particular course I'm playing...It will have a big impact on my game going into next year.

Look at guys like Kenny Perry, he has great difficulty hitting a fade...great technology for the guy who can use it...

Very well put.

I still like drivers that sit maybe a agree open and you can't change. I don't like this change of face angles ect. If the tec was wrong about it changing by 30 yrds ect, people would be sueing, i would think. But for the avg person who swings it different everytime, a club won't make the difference.

The answers have been good but I wanted to add that changing the weight also changes the CoG a little, too. Weight in the heel will effectively make center contact a bit more "on the toe" and as we all know toe hits want to draw.

Additionally it's a tad easier to "close" the toe with weight in the heel, but I think they work almost in equal proportion.

Hmmm. OK. Ihave a much better understanding now..Thanks. so its not all BS.
