You're adjusting your Posture to a Fixed degree of Elbow Bend. The problem with this thinking is that you may have enough Elbow Bend to get a Clubhead with a 60" Swing radius through the Release and Impact Zone before the Right Arm Straightens, but not a 70" Swing Radius. Try adopting the same Posture at Impact Fix for each club with an On-Plane Right Forearm, and so, the Major difference between Driver and Wedge is distance from the Ball and Elbow Bend.
If each club has a built-in degree of Shaft Lean, with a constant ball location, then theoretically, our hands would be in a different location for each club at impact. A wedge would have hands more Forward than a Driver. This might lead one to think that you need more Elbow Bend for a Wedge than a Driver. But Hands more forward for a Wedge has a direct relationship to Stance Width. If the Hands need to be Farther Ahead, then Narrow the Stance.
Thinking out-loud: But this also is misleading for two reasons. First, The more Elbow Bend of the Driver is reduced by Higher Hands. With higher Hands, the Hands need to be farther from the Body. Second, the Shoulders are more open at Impact with a Driver, and the Left Shoulder is farther from the Ball at Impact with a Driver than with a Wedge.
So, the 3" of more Flex at Address for a Driver than a Wedge is augmented by Hand Height and Shoulder Turn. However, you Still have Reserve Flex because the Hands with a Driver aren't as far ahead of the Ball as they are with the Wedge. This reserved Flex may be just enough to get the Driver through the Release and Impact Zone before the Right Elbow Straightens.

The “flatter” the Plane Angle, the more Shoulder Turn is required to put – and keep – the Right Shoulder On Plane. And vice versa.

And,
Quote:
7-16 KNEE ACTION Knee Action is classified on the basis of (1) combinations of bent and straight conditions and (2) the Reference Points selected at which these combinations occur. The combination and the Reference Points selected will determine the slanting of the Hips during the Pivot. The slant is up in the direction of a straightened Knee. The slant of the Hips affects the degree of Hip Turn. Actually, the primary function of Knee Action – as with Waist Bend – is to maintain a motionless head during the Stroke.
The proper amount of Knee Bend is determined at Impact Fix (7-'8') by the distance the Hips must move to allow the Right Forearm to point at the selected Plane Line per 2-J-3 and 7-3. The amount of Bend will also determine the amount of Backstroke Turn and Downstroke Slide. The amount of Bend will also determine the amount of Backstroke Turn and Downstroke Slide. The less Bend, the more the Pivot and Hip Slide will be restricted in both directions and the more upright the Plane tends to be.

But all of the Above is Controlled by the Width of the Stance. With a Narrower Stance, for steeper Plane Angles, Hip Turn, Weight Shift and Knee Action are all interrelated and reduced a similar amount. So, if you kneed less Knee Action throughout the Stroke, then Narrow the Stance but the Amount of Bend was established at Impact Fix and you'll find this to be practically the same for every club.

7-8 THE FIX If there is one mechanical imperative in the Golf Stroke, it is the CORRECT IMPACT ALIGNMENTS. There is no advantage in leaving these to chance if they can be consciously defined and selected by a preliminary positioning. See 3-F-5, 8-0, and 8-2.
There is one imperative definition – except with 10-9-B, Impact conditions are not the same as in the Address except for Clubshaft angle. The most important single difference is that the Left Wrist is Bent at Address but not at Impact. Therefore precision alignment of the Grip can be taken only in the Impact position. Secondly, the Left Shoulder is higher at Impact so the player must be positioned accordingly for proper Shoulder-to-ball distance.
A further advantage of a separate and clearly defined Impact position is that the players have presented, right before them exactly what they will be striving to achieve at Impact. Not merely a vague approximation of the Clubface alignment, but the exact relationship of every single Component. And the opportunity to familiarize themselves with the correct appearance and the correct Feel. And Fix them in mind with more and more precision, especially regarding the Hands. They must appear to be near, or covering, the Left Toe – nowhere near the ball. That will, except as required in 10-8 and 10-9, change their relationship with the ball but they will still be in mid-body location. Move back and forth between Address and Fix until you see that. That difference separates the Pro and Hacker. Much effort and poor results is the giveaway. Without exception. In-put Out-put Power Ratio also is utterly dependent on Hand Location at Impact. (The Flat Left Wrist -2-G and 9-2). Study 4-D-1 and 6-E in this connection.
