To restore fairness in fixturing I think I'd prefer the US conference system but with a twist.....
2 non-fixed conferences
25 games, same conf play twice, other conf play once etc
The twist is the conferences are decided each year based on ladder position (end of H&A)
e.g.
Conf A. pos 1,3,5,7,9,11,13,15,17
Conf B. pos 2,4,6,8,10,12,14,16,18
