I've been using mostly Ilford RC Pearl and FB Glossy. I would agree that neither of these is great for toning if you want a very noticable effect. But I do like the effect of a 1:20 mix selinium toner; it just deepens the blacks a bit. I've had much better luck toning the Ilford Warmtone.
I sepia toned some Forte FB Matte Warmtone once, it turned bright orange! When I've tried to sepia tone the Ilford Glossy FB, it takes forever (hours) to bleach, and the effect is a very, very dark chocolate.
I have been trying Arista RC papers recently. It is available through Freestyle (
www.freestylesalesco.com ). It saves you about $10 on a pack of 100. I like it. It seems to respond basically like Ilford products, and in fact, there is a prevailing rumor claiming that Arista products are made by Ilford, and packaged generically. Ilford denies this, but I've heard it from many different sources. Whatever the truth really is, both Arista film and papers seem very similar to Ilford film and papers.
While I do really like FB Glossy for display, I go though so much paper that saving 10 cents a sheet on the Arista really adds up. I use it for working out the print and snapshots, and then when I've finally got it close to looking the way I want it I switch to the FB, and figure out the differences. The quicker processing and wash times of RC ( vs. FB ) also really adds up quickly.
