[r-t] Caters stimulus package - new methods

[Mark Davies]

Following posting of this:

    Oystercatcher Little Delight Caters
    5.9.3.1.9.5.7.369.147.9.7.169 lh 1

I realised one thing which makes Caters treble-dodging type methods more 
difficult: it's not so much the need to adopt an Alliance or Treble 
Place path, but the inherent falseness due to the negative nature of the 
standard course end of eight working bells. Whilst you can get 
reasonable compositions in these types of method, the fact you have to 
struggle a bit to do so compared to e.g. Bristol Royal, is a bit of a 
dampener.

A quick computer search returns things like this for Oystercatcher; no 
doubt you could do much better with a more adventurous, hand-crafted 
composition, but it shows the extent to which the falseness hurts:

I had a quick look for good methods based on a 12-12-34-34-5-67-67-89-89 
treble path before receiving an email from David Hull in which he listed 
a good number of excellent examples created some years ago - rather 
pipping me to the post. He asked me to forward them to the list since he 
has trouble posting here:

a) 3.9.3.1.9.25.7.1.5.9.3.58.1.9.7.1.7.9 lh129
b) 3.9.3.1.9.5.9.67.34.1.5.1.9.7.1.7.9 lh129 (nice Bristol-type features)
c) 3.9.3.1.5.9.7.36.47.3.1.5.9.7.1.7.9 lh129 (some nice features in the 
blue line)
d) 3.9.7.6.7.2.5.3.7.5.8.3.4.3.1.7.9 lh129 (has a vague feel of Orion 
about it!)
e) 5.9.3.1.9.5.9.3.456.7.1.5.1.9.7.1.5.9 lh129
f) 5.9.3.1.9.25.9.1.9.1.58.1.9.7.1.5.9 lh129
g) 9.3.9.45.9.27.5.1.9.5.38.1.56.1.7.1.9 lh129 (quite dynamic blue line)
h) 9.3.9.47.9.27.56.1.9.45.38.1.36.1.7.1.9 lh129
i) 9.5.3.6.7.5.9.1.5.9.1.5.3.4.7.5.1.9 lh129

The methods are all based around a Double plan, but (since this only 
generates 4-lead courses), symmetry is broken at the hl/lh. Obviously 
you can swap the 189/1 hls and 1/129 lhs as you choose.

He says he only looked into compositions for the first one, and produced 
the following:

  35642           X       -
  64352       -           -
  56342897    -   4
  35642978        4       -
  64352       -           -
  23456       -   X
  23456789        4

  X = 2.3.4 (6 leads)
  In courses called X, calls at 7 and 8 are really at 5 and 6.

He said, "This seemed pretty acceptable, working around little bell 
courses in the main," and I have to agree. Definitely looks worth 
ringing - I suppose the question for David is, why hasn't he??

Anyway - a good start, Ander, to your challenge?
