Ya I was doing those for 70 crafting and then I realized that I could flip for the money I would lose on tarias and still get the level much faster. Needless to say I changed to the silver crafting. idk depends on how good you are at making money otherwise If you're going to do silver crafting, you're better off doing unstrung symbols. It's only 2.5 exp less per bar, with much less loss. (Current GE price for symbols of 128 compared to 26 for Tiaras).
