Ohhh, yes - the 25k (orange covers) ones are definitely the best for detail and actually finding things.

I remember me and Mrs G going round with a touring map with the whole of Cornwall on it many moons ago! Still - we DID, surprisingly, find Boskawen-Un, the Merry Maidens and Tregiffian with it..! Bloomin travesty, it were... ;o)
