Not normally. Usually by the time I'm ready for making a fibre print I've made it a few times with RC. The 10 minute times I think are just the high end of the range. That assumes old fixer. You're likely better using fresher fixer in a two bath setup. That way the times won't be so long and hopefully it'll be easier to wash. Also I think those 10 minute times are used at paper dilution. I don't dilute TF-2 for either paper or film.
