Good to know, I'm looking at a driver that has a moveable 12 gram screw so glad to hear it will actually have some impact. I just remember Tait saying it wouldn't matter. Maybe because he didn't have a driver out with moveable weights, or maybe because at that time we were talking about smaller amounts of weight.
Very well could be, but as I said to Rob Steve is not shy and would bring to the forum himself, well at least normally. He is getting long in the tooth now.
Weight placement does influence ball flight, but only if you allow it to. In other words the golfer can over ride it with their swing. The way weight bias works so I'm told is it moves the center of gravity more towards the weight side.
So, more weight towards the heel moves the COG towards the heel essentially allowing for more of the face to act similar to a toe strike thus 'gearing' the ball back to the left. But as I mentioned if you leave that face wide open with an out to in swing no amount of weight placement will help.
Would that be (with a 12 gram weight) the new Cobra F7 driver that will be out in mid January? That driver has 3 weight ports (two 2 gram weights and a 12 gram weight). You can move the 12 gram weight front, back or heel to change the ball flight from lower, higher and draw. I'll be demoing it when it comes out.
Still own the Amp Cell and Bio Cell and have both set to max loft for most closed face angle, but would like to be able to have the ability to move the weight to the heel for more draw bias help.
All things being equal moving weight around on modern drivers works. Now a lousy swing can certainly counter act this to a certain degree which is why for many years I have been saying to fitters that you can't properly fit this type player. They must have a semblance of a repeating swing.
No actually looking at an old Callaway Razr Fit Extreme. I like that the face can be opened 2.5 and with the 12 gram weight in the toe hope for a fade machine.
Just copy the Triton....seems to be getting a lot of press....
Oh, make sure u let the usga in on it! Hahaha

I almost got the ban hammer in FGI a few years back for suggesting this concept in a thread. I threw it out for discussion that club fitting was somewhat wasted on higher handicap players. Just recalling. 
Bangoman Steve...I was banned silently from fitters buying Geek because they thought I was not defending their position concerning their sales. T hey know you and I are correct they just won't admit it. It was a fitting organization. Not all...but quite a few.
So many truths about this game that become apparent via age and experience. It wasn't that long ago that I could not wait for the new models of everything to come out thinking they were better. I no longer ho around because I think a club is going to help my game. I know I can adapt to whatever is in my bag and shoot to my ability eventually with them because my game is basically find the fairway, advance the ball toward the green (sometimes on the green) and then chip and putt for par or bogey. From the shorter tees I can reach more GIR and land a birdie now and then, but I play to an 11 hdcp with these basics and my drives only go 190 - 200 yds. . I ho clubs now out of boredom and nostalgia. As I age, I become more attracted to older stuff and still believe that the Eye 2 irons were the best design to come from Karsten Solheim. The equipment selling industry peddles so much bullshit (no offense intended) about how much the newer stuff is going to improve your game and it is so exaggerated. Sooner or later, most of the golfers I play with will or have realized that they can play well and enjoy this awesome game with clubs from nearly any era.
Agree with Uncle Steve. However, I have noticed that the better the player, the more the moving
weights, etc. matter for fine tuning. Also, if you move a 12g with from the heel to toe, there is
effectively an apparent 24g change noted. The more you 'let the club do the work', the larger the difference.
JMHO.
