Not all of them -- the MP-PK is the one that I'm suspicious is over 
the line.  (You can see why I'm reluctant to say too much.)

No, from my experience it's a combination of high load and binder -- 
the stuff needed to stick the pigs to the gloss papers.  Eboni and 
the other matte paper only inks can get by with very little 
(virtually no) binder on matte papers.

The 1400 and Eboni-6 are a very happy combination.

My conclusion is that it's a conbination of high load plus binder 
that makes an ink more prone to clogging.  Keep in mind that I want 
NO clogging at all.  So, if an old PK has a single gap in the nozzle 
check after sitting a week, and the new PK does not, and this looks 
like a pattern, then I'll simply avoid the older ink. I have a very 
low tolerance for clogs.  (Note that most of the recent problems I've 
seen reported are most likely air or foam in the head, not clogs.)

You might also note that Epson has moved the black ink to a position 
between the yellow and light and light cyan.  The Ks are probably 
best isolated from the other high load inks even on the parking pad. 

If I sense that there is a potential problem with an inkset, I don't 
want to be associated with it.
