If you want something fun for toning try Moersch Carbon Toner. Take a slightly over exposed print, bleach in a 1+30 dilution of Moersch Bleach until you start to see detail in the overexposed shadows, pull, rinse thoroughly, and tone in Carbon for 30 sec or so. If you then place in Selenium, after rinsing thoroughly again to remove any trace of toner, just enough to sharpen the blacks, pull and rinse again, I think you will be quite surprised at the richness of the earthy browns and golden tones. This is quite dramatic on FB paper, particularly on Foma paper. I have yet to try Moersch Sulfer Toner, but thats next. Have fun and experiment, experiment, experiment...
