I have found very little use for RC papers other than quick and dirty prints, contact sheets for 35mm and Postcards.
The knowledge gained in printing an RC print is in no way useful or applicable to the FB print. The RC print may suggest burning/dodging is necessary but the amount or degree is not transferable.
A print that maxs' out in 1 minute of development cannot reveal the nuance's of a FB print that can be split developed or where the amount of development directly applies to the final print.
That's what I think this week.
