<br>
All the "standard" extensible methods I know of have the same leadhead order in all their extensions:<br>
<br>
Plain Bob: +1<br>
Little Bob: -2<br>
Kent: -1<br>
Yorkshire, Cambridge, Pudsey: +2<br>
Bristol: -8<br>
<br>
(Here I use a notation where +1 = a or g LH, +2 = b or h etc).<br>
<br>
It might reduce the size of the problem posed in my last email if it were only necessary to consider a single leadhead order.<br>
