it's the Bury situation that makes things difficult.
The league won't want to run with 23 clubs again if it can avoid doing so, and promoting Barrow seems a good way around that.
Suspect it means our division would need to run with 23 instead, as I can't quite see how NLN/NLS could only promote one between them, unless someone chooses to take a voluntary demotion for financial reasons in the AGM Cup.
