UCAS choices

Applying to engineering courses
My choices:
Imperial, UCL, Bath, Queen Mary
I'm stuck on what to put for my 5th choice because it's likely that I'll get rejected from both imperial and UCL. I would like to study at bath, but I'm not sure how I'd do living outside London. And queen Mary I'm either gonna firm or put as an insurance. So this last choice is key.
I've been looking at:
Manchester - civil engineering with integrated foundation year
Bristol - design engineering (new course)
Kings - general engineering (relatively new course)
The first 2 are outside London, so I'm not keen on them, but manchester ranks highly for engineering. Kings is in London, but isn't as "specialised" for the course...?
