Thanks very much, I think soft case will be perfect. It's only going in a case to protect all the fancy track bikes from knocks anyway. (They will also be in cases).
Defintely no need to protect Brompton at all, just leave it folded, no packing at all.
It's the actual bike you need to worry about,in fact, not bothering with even a soft case allow you ample money to put toward protecting the more expensive bike.
