You can pay for guaranteed stop, but it probably just guarantees you'll lose it since you'd probably want to be long gone by the time it's hit. These SB guys aren't daft and they won't give you much that might work to your advantage.
Again, thanks for all your feedback. As I said to Toknees, you have both offered some great advice. It's been nice to chat, a one to one sometime. actually can't see that happening, looking at the amount of posts you've had, it seems like you are a very busy man
