gentelman, today i developed my first fb paper :-)
i just cut a sheet into half and take the same exposure parameteres of the rc development. just to see how diffrent it is.

and it is different :-)

my imaginary workflow for 8x10 papers:
i will do first prints on 5x7 rc papers to see how does the negative looks like on paper.
store them over the week!

at weekend i will grap out the photos and watch them a second time.

if i like a print i will enlarge it on fb paper using conventional workflow with tests strips form the same fb batch...

lets give it a try...

best michael and thank you for your great advice
