I too, have just tried the Cott 320 and it is magnificent. It is the nicest paper I have worked with. Luxuriant comes to mind. I don't use oxalic acid with it. I balked at the price at first but then when it comes right down to it when you think of all the work one goes through to get to the point when you actually make a print.....it really isn't that much more. The results negated any qualms I had about price.
