drchip,
Thanks for the update.
Have you found that your divot pattern is exactly the same with all your irons now?
I ask because, with longer length clubs, longer shafts would normally increase the swing arc which would mean a more sweeping action.

@Matt1960:

I've already found a strange phenomenon with these clubs: if my brain thinks I'm hitting a particular numbered club, it acts as if that club is like the ones I've always used (that is, classic graduated clubs). That is, I'm much more likely to have a shallow swing plane or sweep the new 3-iron than the 6-iron, or more especially than the 9-iron or wedge. Since the shafts are the the same length and the weights are the same, it appears that I am clued in by the different areas of the club faces. Somewhat like a traditional set, the faces get smaller as the distances of the clubs increase, my brain picks up on this, and swings accordingly.

Evolutionary biologists have recognized a characteristic of the human brain that allows embedding of certain types of information so strongly that it seems to act almost like a gene. They have named it a "meme". I think it will take me a while to overcome my graduated irons meme, and create the same divots with all the clubs. By the way, the more I "sweep" this new 3-iron, the more I see the pattern of lower, shorter flight that Chuck described. It seems quite important to swing the same with all the sticks, that is, down and around to the left (for right-handers).

This phenomenon leads me to speculate that single-length clubs would be especially good for beginners, who have no club "memes".

The experiment continues.

drchip,
Yes, I am sure it will take a while for you to retrain your brain to the new clubs.
I suppose the next question would be, that as you must be swinging slightly differently with the straighter faced clubs, how is the swing different?

Day 3 on the range with single-length "1 Iron Golf" irons:

I am becoming more and more convinced that any deficiencies in these clubs are from mental machinations on my part. In my former profession (I'm a retired surgeon), studies show that the placebo effect is extremely powerful, frequently more powerful than engineered therapies. The in-grained ideas I have had for several years (I took up golf about 6 years ago) about golf clubs and what one could expect from well-struck shots, and how to generate those shots, have a very controlling effect on my approach to the swing, like the placebo effect. When I very carefully use the same Rotary technique on all the single-length irons as I do on my six iron (same ball position, same swing plane, same swing length, same effort level), the results are spectacular. The best practice technique seems to be concentrating on the 3-iron. Once the 6-iron swing can be used reliably with the 3-iron, the others just seem to fall into place without any effort (as least as much as my limited athletic ability allows). The most amazing thing is how easy and accurate chipping and short pitches are when using a full six-iron posture and never choking down, only altering the length and power of the swing.

Of course, I sought out such clubs because they seemed logical to me, so some of my positive response could be confirmation bias.

Drchip,
One of the things that intrigues me, is that when we discussed same length irons a couple of months ago, some people indicated that lofts would need to be adjusted to compensate for lack of distance in the straighter faced clubs.
I never thought that was a good idea, and the more I think about it, the more I think that if you could retrain your brain to swing exactly the same with all the irons then surely you would automatically deloft the straight faced irons by swinging with a less wide and less sweeping action.
As I have indicated before, out of interest, I would quite like to see statistics from robotics, but that appears unlikely to happen reading your correspondence with the USGA. 
By the way, if I were to go down the same length route then I would probably choose 9 iron or wedge length rather than 6 iron.
