Sorry to reply to myself (bit like Bernard Taylor in the RW), and for the 
blank message cock-up, but I was thinking a little more about treble-dodging 
major methods with 123678 made when the treble goes through 4-5.

A bit of playing around gives an intriguing unrung surprise method:

&-34-45-56-2367-34-45-56-7,2 14263857 (or &-34-45-56-2367-34-45-56-1,1 
18674523)

Both have a reasonable 42 <4-runs>, and ABD falseness.  But look at the 
symmetry!  Not only is the method conventionally double, each quarter-lead 
is also double.  Neat or what?  The symmetry's so good it ought to have its 
own name.

Are there any rung treble-dodging methods with this property?  What about 
non-treble-dodging? Double bob would be an example.
