In case anyone's interested, after visiting both schools we've decided on leaving St Peters for Bootham.
St Peters has great facilities, it's true, and good results, but the 'feeling' of Bootham is just so much nicer. I love their ethos of producing young people who will do good in the world, rather than the more individualistic 'me me me' vibe at St P. And the music facilities are better than St P's.
The attitudes of SLT are also interesting. At the Bootham open day the head, deputy head and music director all came to speak to us, and directed most of their interest at DS.
Meanwhile, there had been no interest or info from 'big' St P's about moving up, and when I did manage to organise a tour and a meeting with the head he just gave us a 20-min sales spiel, directed totally at me, and didn't even look at DS or ask him a single question.
DS does have good friends there, but philosophically said 'I've only known them a year. If they're going to be good friends I'll keep in touch anyway, and I'll make new friends at Bootham'!
