Steppe or other ?

Another mystery Gull today, Feb 10, 2012 on Herakleion Harbour. Is it a second winter? If it is Steppe or Caspian? The fine bill without obvious gonys excludes michahellis and armenicus and looks not unlike 1st summer Ring-Biled?

Comparing with michahellis looks a bit smaller, same grey:

Comparing with Caspian the bill is shorter, also legs shorter and possibly heavier:

So what?
