I've decided to finally finish this thread, bit of writer's block here, but we're done now. The fares and contactless set-up relates to travel from 2 January and 11 January 2016 respectively for travel before then options 4 to 6 are more expensive, some considerably so.
Please feel free to comment or suggest improvements.
