The problem with the Lowland league is that it'll be set up with a bunch of East of Scotland and South of Scotland sides. It has been proven time and time again (more so the south of scotland league) that the East and West Juniors are superior. Auchinleck or Linlithgow should be in the lower league or it's not worth having IMO. The last 4 HL sides that Auchinleck met in the Scottish they have beaten, that to me shows they have one of the best non-league sides in Scotland.
The Lowland league should have 2 or 3 South of Scotland teams only, they really are garbage! Fill it with more teams from the Juniors and set up a pyramid system below that but in regions like it is just now.
