Digital BW, The Print

Well, things are begining to look up, after speaking with the lab 
that made the profiles today, they gave me some tips that were 
new to me and I will share them.
Rather than set the profile in the epson print box, they suggested 
setting the profile in the Mode, convert to profile.
That made an enormous difference, in getting close to neutral, 
also setting View to custom for the monitor with the new profile, 
allows me to see subtle b&w adjustments on the screen.
While changing the brightness, I am seeing a pretty drastic color 
shift to Cyan, the lab had not experienced this.
Any thoughts.
