I wrote down the following sentence. But I think it's quite awkward. Besides, Google tells me that the clause which I don't find him to be occurs only twice across the internet.
He'll do this if he's smart, which I don't find him to be.
I was trying to combine two thoughts into a single sentence.
I don't find him to be smart
He'll do this if he's smart.
Is there an alternate way to articulate the thoughts in a single sentence that's more elegant?
