Asphalt felt, rosin paper or glue?

Q: When installing 3/4 x 4 inch, unfinished Brazilian Cherry over 3/4 plywood subfloor, would you suggest asphalt felt, rosin paper or to glue the cherry pieces to the subfloor?

A: I would go with the felt and forgo the adhesive. You don’t really need to consider using adhesive unless you are installing 5 inch or wider.
