Thanks for the feedback, Philip. A few points for me to respond on:

It may well be possible to produce similar palindromic structures with
my plan, but this wasn't one of my aims. I know Pipe used that idea and
the 2nd/tenor pivot leads in order to maximise music, and it is indeed
elegant, but I took an alternative approach - brute force the best
methods. This yielded non-palindromic splices.
If you look at the Pipe methods, the run density is not very even - the
Phobos and Deimos pack in large numbers of runs, but the Maypole and
Zanussi aren't so great. It is possible to improve on these using
library methods in non-palindromic structures. Palindromicity doesn't
necessarily yield the absolute best results. I accept it makes it easier
to ring and call, of course!

Yes, Pipe is much better than my efforts by this count. To be honest I
didn't look at the big runs at all - I optimised purely for 5-runs. I
think in this I do quite a bit better than Pipe. I will take another
look and see what I can get out optimising for 8-runs.

I wasn't fussed about ATW, but the structural reason for the lack of it
is that the alternating parts require different methods to make the most
of them. In the Pipe peal, all parts are the same, and so ringing the
same splice to each part works well, and this naturally delivers ATW. In
my peal, half the parts are rung in reverse, and so runs will appear at
different strokes: a method that's optimal in a given lead for one part
will not necessary work so well in the other part.
So, I optimised the method choice carefully for the "odd" and "even"
parts, and therefore we get different splices and different methods in
each, and the peal can no longer be ATW. I would argue that this very
feature is what makes it a sculptured whole, but each to his own taste!
I do have other arrangements with more methods, and even less work of
each, which increase the 5-run counts again, however these start to look
much less accessible - I wanted something that a half-decent 12-bell
band might think they could have a crack at.

The individual methods absolutely were carefully selected, but only from
the existing libraries. I used the following protocol:
1. Start with the entire rung library of single-hunt Alliance and TD
methods.
2. Filter these to retain the "best" methods (about 570 of them), rated
by structural properties and music in the plain course.
3. Brute-force these into the "odd" and "even" courses of the peal plan,
separately.
4. Further refine to reduce the number of methods, and favour as many
"well-known" methods as possible, without unduly reducing 5-run counts.
I didn't look to construct new methods for the composition. There is a
good chance this could yield improvements. Howver, it is nice to give
library methods an outing from time to time though - I reckon
popularising methods like Counter's Creek and Fallen Angel would be a
good spin-off. I certainly was not constrained by 'bog-standard
“regular” treble-dodging maximus methods'!
Anyway, in the main I accept your criticisms, and I will work on
increasing those 8-runs.
