Law Choices 2025- Do I need a backup for competitive application?

Im applying for law this year and unsure of where to go for a competitive application and whether I actually need an insurance choice as my careers teachers advised me against it.
GCSE: six 9s, two 8s and a 7.
Predicted grades: A*A*A*
I’m thinking of any of the following to apply:
Cambridge, Bristol, Nottingham, Manchester, Sheffield, Exeter, Warwick, Durham, Glasgow
Do I need an insurance choice, and would anyone suggest any of the following are better law schools and for an all round better experience?
Thank you sm!

I’m also applying to five competitive universities this year to study law (Cambridge, Bristol, Manchester, Nottingham and Leeds). I’ve been given various pieces of advice on this issue by careers advisors, teachers and professionals in the legal industry. To sum it up, you essentially have two choices:
The first is to have one or more safety choices. Your predicted grades exceed the minimum needed to study law at any UK university, but ideally, your insurance should be at least two grades lower than your firm choices. For you, this might be anywhere between AAB - BBB. If you are eligible for contextual offers, this would allow you to still apply to more competitive universities (e.g. Nottingham), but have the contextual offer act as your insurance. If you are not eligible for contextual offers, you may want to think about applying to universities that require slightly lower grades for their standard entry requirements (e.g. Leicester asks for AAB).
Your second option is to take the risk and apply to competitive universities without a solid insurance choice. If you do this, you have to be prepared for the possibility that you a) may get rejected from all of your choices and b) would have to go through clearing if you didn’t meet the high entry standards for your firm or insurance choices. I wouldn’t advise taking this route unless you wouldn’t mind applying for another course at a competitive university through clearing, studying law at a university with lower entry standards or taking a gap year.
Personally, the route I have chosen to take is to apply to competitive universities and accept the possibility of rejection or going through clearing. This is mainly due to the fact that I am eligible for contextual offers of AAB at three of my university choices and a contextual offer of AAA at Manchester (obviously Cambridge asks for A*AA). Although this would likely mean that my firm and insurance choices would require the same grades, I feel as though it is highly unlikely that I will achieve lower than AAB at A level, even if things go wrong in my exams. If there is a course that I like at a university I wouldn’t mind going to, I would be prepared to go through clearing, but otherwise I would probably just take a gap year and resit.

Thank you so much- that’s really helpful.
I might consider just taking the risk as I don’t know if I’d enjoy being at universities other than those.
I don’t have any contextual offers but Sheffield says AAA which is slightly below the rest.
