Thanks for all your comments. DS1's prep sends 2-5 to Eton most years but only 1 to Winchester about every 3 years - there are therefore few parents at any time with experience of Winchester to ask our endless questions of ....
Match tea etiquette doesn't really faze me that much unless it's symptomatic of a behaviour throughout the school; I simply don't remember a single match tea / service thereof in my time at school but do remember how we were taught at home to take people's coats, serve drinks etc, so I hope DS1 will follow suit, regardless of schooling.
I'm surprised too, happygardening to hear any negatives about the pastoral care at Eton - everything we've heard is what a strength it is.
So for DS1, his view is that Winchester's plus points are its sense of quiet and beauty, he thinks that the teaching there is better (not sure why as he's never had a lesson in either school!), and that he wouldn't be forced to do sports he hates (team sports basically - see no match teas for us!!). He sees Eton as having better facilities (he lives for drama, music, art and history), better subject choice in Year 9 and having more societies, he likes the idea of his own room and it's closer to us so he could come home for family birthdays etc (30 mins by train rather than 1 hour).
He's likely to take the scholarship exam whichever we choose.
Eton seems like a very well-oiled, slick machine of a school whereas Winchester appears more quirky. I suppose our over-riding concern about Eton is whether he will become really arrogant by the end which is the stereotype, of course; and with Winchester, we worry that whilst he'll have a lovely, gentle time thinking in his peaceful meads through adolescence, will he actually really have the wherewithal to make good in the world afterwards or will he be always dreamng of pastures green ....
Lengthy ramblings, eh, and only a fraction of the mullings spinning in my head. Prep Head also sees DS1 happy at both schools (marginally in favour of Winchester because of DS1's intellectual approach although the only reason we looked/applied to Eton was because he suggested it as a great fit); he's going to chat properly when the chaos of Sports Days etc i over.
So, no-one around with a child in both schools???
