Object bind to surface jitter

[Booclay]

In Object Bind operator, try changing sample from "face hybrid" to just "face".
That way, the operator will look at your mesh as it is, and not simplified version.
Also, you can try and add turbosmooth to your mesh (so operator have more polygons to work with), and some Ty Relax (so you make smoother all the sharp angle areas).

I tried it... it seems like it's smoother now.

Ace, thank you. great info. I'll give it a go now.
