I find that the papers that gives consistently fine results with ease of
operation are Saunders Waterford and Fabriano Artistico; both are widely
available at good art shops. They also work well for cyanotype and platinum
and platinum/ palladium. On reflection, I now use them for nearly all my
work with processes involving hand coating. The hot pressed versions
should meet your need for a smoother paper.
