The extent has been used to increase the record for the number of treble-dodging minor methods in a peal of seven extents, up to 349.

The composition is quite rule-based, with the same under/overwork when a particular bell is pivoting. What's more, you've huge potential for splicing in very large numbers of treble-dodging methods, as each under/overwork is very interchangeable...
Letter choices (options on same line are lead-splices so can be interchanged at will within same extent):
a 34-34.6, -34-6, -5-6, 56-34.6 3-5.4 -3-456 b,c -34-4, 34-5.4, -5-4, 5-5.4, -34-456, -5-456 -3-6 3-3.4 d,e 3-34.6 -3-4 34-3.4, 5-3.4 For underworks, just reverse the overworks: h=a reversed f=b reversed i=d reversed etc
Richard Smith has developed the idea the produce the 'Smith Magic 720', which is a three part PABS 720. Richard writes:
For 3-part comps using this plan, you need three over
works and three under works, however only 7 combinations of
these are used. To get a set of 7 real methods, rather than
having to have pretend half-lead calls, it is easiest to
choose overworks with the same effect -- e.g. Cambridge/
Carlisle/Castleton, Norwich/London/Ely, or Kent/Oxford. To
get a composition with at just 3 Homes in this manner, a
mixture of regular and irregular methods are necessary. Here
are comps using Cm/Cl/Cs and two using No/Lo/El:

Lead-splices can be easily added for Luton and Bakewell.
Kent/Oxford is rather more dull as the seconds place

Notwithstanding the comment above, it is possible to get
3-part compositions with only 3 bobs Home using just regular
methods: it's just a rather less formulaic exercise. Here
are two such compositions.

Sorry about the method balance in the latter composition --
it's the best I can manage. (Though it's easy enough to
vary which over/under-works are over represented and which
under.)
Of course it isn't just 56hl underworks and 12le overworks
that have six-lead splices, even if most are. For a
one-part comp when you ideally want five underworks, this is
enough of a problem to rule out other over/under works, but
in a three-part comp, this is no big issue. For example,
123456 ag ga

142563 af fa af fa = Cotswold TB (216 changes)

And then there are plenty of things besides 6-lead splices
that can be done below the treble. How about putting this
grid-like splice under?
