for what its worth, I'd go for
SPL - 16 teams - play each other twice 2 down automatically 1 more in round robin playoff
Div 1 North - 16 teams - Champs promoted, 2nd in round robin playoff
Div 1 South - 16 teams - Champs promoted, 2nd in round robin playoff
Make up games by bringing back the League Cup - 8 groups of 6 seeded (48 teams), play once (like UEFA Cup), top 2 progress to Last 16 of League Cup. Lets the wee teams get 1 or 2 games a season against top flight
Div 2 North? - Highland League Maybe and Div 2 South being South of Scotland League ..... start of a pyramid structure
Back on topic though .... make Hearts the team affected by 3 visit problem and cut the moaning of the Old Firm at us ..... we should have been the seeded Top 6 when guessing for the split who would be Top 6 this year
