Digital BW, The Print

ok, someone just told me not to worry about other inksets until I was 
ready to switch.  I'm ready.  My CFS is gone.  I've got color inks in 
my 1160 and I'm ready to go with a new inkset.  I've used MIS VM for 
more than 2 years, got a lot of great prints out of it and a large 
number of bad ones as well.  The jerky tonal space causes lots of 
posterization which cannot always be fixed (though my 21 stepwedge 
always looked perfect).  Do the UT inks and new curves give a 
smoother gradient?  What about FS and Jeff Randall's MIS Full 
Spectrum Partitioned Quad Workflow?  I only print the MW warm mix as 
it is so I don't think I need VM, but I would like a smoother 
gradient etc.  Anyone still use that?  If so, willing to post a 
gradient somewhere?  I know this is probably the wrong place to ask, 
but what about the Lyson stuff?  Any other thoughts?  I'm not willing 
to pay for Peizography since I could almost get a 2200 and IP for the 
same price. 

thanks for all advice,
