So it was obvious, and I did miss it. Thanks. Sounds like they meant it to be like residuum, but I think I'm going to house rule that. I agree that ritual components should be light (so as not to hose ritual casters for their choice), but weightless is a bit much for early-tier ritual gear. Maybe ritual components available at a given tier should have a weight equivalent to treasure available at each tier--50 gp per pound at heroic (gold coins being the standard), 5K per pound at paragon (platinum), and 1/2 mil at epic (astral diamonds/residuum). Maybe a little less at epic.
