I've gone through 4 of these machines, and none of them had more than 
3 ink channels that printed completely banding-free. One of them was 
the gloss channel, so I've used it for that critical LK in a K4 all-
in-one configuration. I don't see having an extra channel to choose 
from aa a liability. OK, if you're going for a single tone, matte-
paper solution, you don't need it, but OTOH having the option of 
setting it up with A) matte K4, B) Gloss K3, and neutral, cold, 
carbon, or deep sepia variations of either, has a great deal of 
appeal to me
