QTR-Quadtone RIP

Hi All,

I just joined in.  I am planning to dedicate my Epson 4000 to B&W  
only, & plan to get the new 3800 for color.

My question is , which ink sets seem to be in favor?  MIS  vs  
Piezograhy?  I am in NEw England, so tend to like buying local.

I tend to lean toward the neutral ink sets, but wonder if anyone has  
tried the SplitTone inks, from InkjetMall  &/or if they actually can  
be used.

Thanks All,

Skip
