This is certainly how I'd learn it if I were to organise an attempt
(see <http://ringing.org/main/pages/method?notation=-4-1.4.3.4-4-&pn-query=Display&stage=6&le=23>).
I find it interesting, though, that each bob (on this plan) affects
either the front three or the back three.

So, is this technically a twin-hunter or a differential? And,
presumably, if I called it in this manner, I wouldn't be allowed to
name the original unprinciple - or is this a grey area in the
Decisions?
