Welcome, unccivil. Please put a first name in a permanent signature line for us to use.

Sounds like you could add deeper sisters on only one side and save a good bit of work and some dinero.

But now that the subflooring will be removed, you might reconsider your mid-span bracing. Far more bang for the buck there if you can get the old joists to flatten out.

Can't comment on that at all without more information.

Seen what? Sistering joists? If you'll look about the site just a tiny bit you'll see that we recommend it several times a day, on average. Very common way to bring insufficient joist structures up to par.

My opinion; worth price charged.
