I suspect the clog has to do with the permeability of the tubing to 
the solvents in the ink, that is, the solvents diffuse through the 
tubing leaving behind the ink goop.  The warmer and/or drier the 
environment, the greater the diffusion rate.  Also note that the 
tubing has a very high surface area to volume ratio, therefore it is 
not suprising to see the problem here, rather than, say the ink 
reservoirs.  

My experience has been that the MIS tubing is more permeable than 
the Tygon brand tubing used by NoMoreCarts.  This result is based on 
almost three years of side-by-side comparison with a CFS (MIS) and 
CIS (NoMoreCarts) on system on two 1160s and the same MIS FS inksets.
