Wow
Many Many thanks guys - especially like the little tips (like that of Greg's). There are a few things I neglected to mention I had, which you have highlighted, and others I wouldn't even have dreamed of!
In regards to the Tent, I think I should be ok in the Bivi, as it should be a top notch one! (given what I paid, I will be bloody angry if its not! - and I'll suggest a new bushcraft hobby of hunting down the shareholders of force ten) although some have mentioned a tarp, I may go for a poncho if I use the M90 and take the advice of others of using 1 item for several purposes.
I will take a camera, although a cheapo disposable one and then if it works pop some pics on here.
Again many thanks, I really appreciate your inputs.
P.S

Overnight temeperatures can easily be minus ten degrees C in Scotland this time of year. It was minus 6 here last night, and I live 100 miles south and at low level.
I'm looking for as cold as possible to test my gear out...sounds good
