Digital BW, The Print

I currently use a 1200 with mis-vm inks and am reasonably satisfied; 
I am comfortable with the process, like the results and problems 
(clogs) are mininal.  I would like to hear from anyone who has 
switched from a 1200 with vm inks to a 1280 using the ut2 inks.  I am 
not that concerned about glossy paper; is there a noticable 
difference on EAM or PR papers?  

I have a 1280 which I use infrequently for color and am wondering if 
it is time to switch.  The UT2 inks seem to be the way to go, but I 
wonder about the relative difference with what I am using at this 
point.
