Digital BW, The Print

Hi all.  I am trying to make a photoshop curve to get to a fairly neutral print.  After about 20 iterations, I am currently stuck.  I was wondering if someone might be willing to look at my curve and 21 step LAB values and let me know where I'm going wrong?

set up is Epson 2200, UT3D with PKN, and Ilford gold fibre silk.

Thank you,
Earl
