Total changes of opinion re winds (5-5)

'total changes' is the definition.
'about turns' can be an answer for 'changes' (about turn is a kind of change). I'm unsure of the 'total' bit.

'opinion re winds' is the wordplay.
I cannot really see how this works, but
're' could be 'about' (I've seen this in another clue) and 'about' is present in the answer.
The remaining letters 'turns' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'of' acts as a link.

Can you help me to learn more?
