The pros of using MIS K4 to me are the cost, the cost, and the 
cost.  Even after shipping to NZ it is at least 5 times cheaper than 
the K3 ink.  Because I can refill carts with the K4 myself, there is 
also less wasteage as there is no risk of another cart emptying 
during the replacement of a different cart.  As i explained earlier 
i refill all carts that are less than about half full whenever any 
cart is replaced.

As for the cons - well I can't think of any as yet.  I suppose 
refilling carts may be a con for some but I am quite happy to do 
that as it is very quick and easy.

You can use the K4's with ABW and I did for quite a while, but I 
find that the QTR results are much better, especially with shadow 
detail.

For QTR, I create my own K4 curves.  Initially I started with Roy's 
K3 curves and adapted these for the K4 inks using an eye-one to make 
various colour balance adjustments and then linearise the resulting 
curves.
