Hello,

I would like to know if the end of the following sentence is correct English:

I am wondering whether it would not be better to write "he attaches central importance, however".
What is your opinion?

Thank you very much for your help.

Did you write the quoted sentence? If not, who did?

Yes I did, Rover_KE.
I have the feeling that my sentence is not very elegant, but perhaps I am wrong.

Your original sentence is fine.

I'd say that not only would it not be better, it would in fact be wrong.
