I see the period after the "pdf" got embedded in the URL.  Here's the link sans period:  http://www.paulroark.com/BW-Info/1100.pdf

First, of course, try some  different Epson driver paper types to see what is available in the driver.  The paper type selection is the main way the driver can adjust ink limits.  Keep an eye on both the dmax and the midtone smoothness.  Too much ink there makes for rough prints.

For the curve that goes into the ICC, use the R, G, and B curve, not the overall gray curve.  In fact, I stay in Adobe RGB when setting up a system and ICCs.  In the PS print preview, set "Photoshop controls colors" and set the profile to the Adobe RGB the file is using.  See the screen grabs in the draft PDF noted above.
