Doesn't Philips comment answer it? For single hunt methods on even or odd stages a plain bob lead end must have a plain bob lead head with place notation 12 or 1n (or 12n or 1 for odd stages). Any other place notation could be considered a bobbed lead of a method with said pn (I know that the definition of calls is considered to be independent of the definition of the method but would anyone really think that Ebor is anything other than Cambridge with a bob at the lead end?).
The original post from Graham was whether or not the term regular was useful. Given the properties of the plain bob lead end/heads then I think it is. In the same way that separating out cyclic methods (which is on the basis of the lead heads) is useful. I suspect that part of the problem is that the complementary term, "irregular" is somewhat pejorative in the way that "non-cyclic" isn't. Perhaps there is a more neutral term (I certainly don't like "standard" the implication being that other methods are "sub standard"). I don't think this a value judgement it is simply a way of classifying methods based on one element of their structure which is useful to ringers, conductors and composers.
Given that "regular" methods form a useful (in my opinion) set as does cyclic, are there any other lead end/head sets that are useful in any way?
