I’d get them to justify exactly why they think you need a Miami. Study the Philadelphia first, so you can field their justifications i.e. the philadelphia:-
Is a rigid collar, so offers firm support and not easily bent out of shape
Is lightweight so won’t be adding to you burden
It neatly cups the chin
It firmly supports the head
It firmly supports the neck, from all sides, especially the rear – IMPORTANT where loss of lordosis is concerned
In fact it is precision shaped for better all round support
It restricts rotation and flexion and other movements which are likely to cause further injury
It maintains a good relationship between the head and the neck, so CSF flows more freely VERY IMPORTANT if you have any kind of Chiari
It’s easy to eat and drink whilst wearing (unlike some of the other collars I’ve tried)
It’s easy to measure for, by the orthotics dept, in the first instance
It is very easy to take on and off without assistance
It is easy to clean
It is easy to fit new linings
Coolmax linings dry very quickly when washed
Coolmax linings are designed to reduce perspiration and overheating
It is certainly the most comfortable and effective of all the rigid collars I have used
The velcro fastening will last at least a year, even with 24/7 usage
It’s flesh coloured, therefore less obvious!
It’s easily covered a scarf
It’s cheaper on the public purse
I rest my case . . . . .
Lol, no I don’t have shares in the company!
