Robert,
I used this information from Scott Martin to figure out the right settings with my Epson 3880

Thanks Alan ... if there was no choice I would certainly have a go using Scott's technique, but since Hahnemuhle, Canson etc., provide full settings for their papers I won't be going near the Epson ones while I'm using an HP printer. It's strange that Epson doesn't provide settings for other printers as I'm sure they could make plenty of money from paper sales.
As an update: I had forgotten that I have sample packs of Hahnemuhle paper and I've tried the textured fine art ones ... all very nice. My preferences would be as follows for watercolor prints:
Museum Etching: This a heavy 350gsm paper with a lovely texture, my favourite
German Etching: Next best, with a rougher texture (and feel to the hand)
Torchon: Very interesting paper with a 'torchon' finish. I will be using this for some images.
Wm Turner: V. nice, but I like the German Etching texture better. The Turner has quite a sharp texture which isn't watercolor-like.
Sugar Cane: A good possible as a Hot Press type paper. It has essentially no texture (just a little
Albrecht Durer: This is a lightweight paper (210gsm) with a very sharp texture that I don't like. Won't be using this one.
So of these the ones that I think I will use are the Museum Etching, Torchon and possibly the Sugar Cane for Hot Press prints.
In terms of gamut and Dmax there's not much to choose between these papers. Of course they all have a fairly low DMax of around 1.6 and they are all weak in the saturated reds, like all the other watercolor papers I've tried. Still, as long as these are taken into account, the look of the prints is fantastic.
