Thanks for the two tongue twisters I didn't know. I've got more chance of success with them while gargling than I had with the grid.

Thanks toast; hope you still enjoyed it though :)

I certainly did enjoy it and you had very good explanations which count for a lot. The grid was very hard but I have found with grids I have set that they are a lot tougher looking back than I intended. And don't think that a lack of comments means anything - good comments are great but look at the stars !
