How many teams should be in the top division of the Scottish Soccer League?

We have had 10, 12, 16, 18 and 20 teams in the top Scottish division of football over the years. 

The argument for a 10, or 12 team division is that then Celtic and Rangers can play each other four times a season and get higher tv views, and get more money for Scottish football. But the other side of the coin is that by having 20 teams in the top division we can get more teams playing the elite sides and developing their players. Also it becomes more difficult for the big Scottish sides to be relegated. So you do not end up with Aberdeen, Hearts, Hibs, Motherwell, Dundee or Dundee United playing in the second tier. 

But for me. I take another view. I would prefer to have a 14 team league with teams playing each only 2 times a season, resulting in a 26 game season. This could massively open up the calendar for teams to play other trophies against teams from the rest of the UK, in cross border cups, or teams from mainland Europe. 

I would love all top tier Scottish sides to play in an extra cross border trophy, on top of domestic league, domestic cup, and European football. So this would spice up the season for Scottish sides. Imagine Scottish sides playing regularly against good English sides, without giving up their own leagues. 

Let me reiterate I do not want to have the Scottish sides join the English League. And I do not want a league merger of the British Leagues. I want to keep our own leagues and cups, and big sides, but play extra cross border trophies on top of what we already have. 

I would love to have 1 14 team Scottish league with 26 league games a season. Added onto that some sort of cross Great Britain trophy, on top of what we already have. 

This would really help Scottish soccer without destroying our football independence.
