People are claiming 3-5 knots extra on the new prop but the
interesting thing about the new prop is that it (in theory) has an

metal blades do so you can overhaul it as many times as necessary.

What's involved with overhauling a composite prop?

I believe after they are ground they are built-up again.

Some also have (titanium?) erosion strip on the leading edge so that
you can replace the strip if you somehow manage to dent it.
