Now things like erm, well one of my old favourites Arran Pilot i if you dig it out when it's young, then of course it stays as it should, cos it's a very very waxy potato but, but I can remember growing varieties like Majestic and things like that and I mean they would never fall, they would never fall in the water but  they make good chips er of the modern varieties I think I'd go for er Kondor with a K er which is a very very good potato and does stay as it is i in the ground but one other thing I think also comes into it.
