A couple of things:

1. While the pros at Address usually have a Bent Left Wrist and their Right Forearm above the Clubshaft (below Plane), at Impact their Left Wrists are Flat or Arched and their Right Forearm is in-line with the Clubshaft.

2. You're right, the pros don't go into Impact Fix and verifty their Alignments (Flat Left Wrist; On Plane Right Forearm; Left Shoulder much higher than Right Shoulder; Clubface position reltive to the Angle of Approach for the Hinge Action they plan to use;...etc.). They start at Adjusted Address, which is in the book. And yes, at Adjusted Address, the Left Wrist is Bent, the Right Forearm isn't On Plane (because the Hands drop closer to the ground as you move from Fix to Adjusted Address), and the Shoulders are more level than their position at Impact Fix. Oh, and the Clubface closes as you move from Fix to AA, too.

It is your choice as to whether you want to begin Start Up from Impact Fix, modified Impact Fix, or Adjusted Address. Starting from Adjusted Address has its advantages for Swingers (most pros are Swingers, which is why you see so many of them use Adjusted Address); Hitters should start from a modified Impact Fix (Flat Left Wrist) with their Hips pre-closed.

General Observation Based On Pro Golfers And NOT A Criticism Of Your Question!

Personally, I don't care what the pros do. I believe that they are basically idiot savants who are born with the gift of Educated Hands which can easily compensate for some of the crazy stuff they do. As Chuck Evans says, "They're skilled hand manipulators." Consequently, I don't find much value in imitating what they do, since my Hands aren't as educated as theirs.
