That's very interesting, Richard.  I was ringing something on a similar plan
this evening :-)  Can you extend the idea to get 420 different
treble-dodging minor grids into a 7-extent peal though?!

So do you think an extent of spliced major on this plan is possible without
using a single every half-lead & lead-end to turn it into a minor problem?
Any ideas on how to proceed anyone?
