The SPL have put forward their plans for league reconstruction: http://www.bbc.co.uk/sport/0/football/20384809
Basically, it's two divisions of 12, which essentially becomes 3 divisions of 8 mid-season. The top 8 SPL teams play each other another twice, the bottom 4 of the SPL and top 4 of the SPL 2 play each other home and away with the top four going into the SPL the following season, while the bottom eight of the SPL 2 play each other home and away again.
If we can't get people to agree on a 16-team SPL, this would be my second choice. It adds some variety for teams like us, and will probably give everyone something to play for towards the end of the season.
Thoughts?
