The shrouds are in good shape
Then, personnally, i would not worry about replacing them at this time. I would add a second adjuster plate to the front to rake the mast back and let it fly.
That is what I ended up doing. I had bought new shrouds and forestay, ended up taking them back to get a shorter forestay and longer shrouds do too length changes.
