I know that the MIS bottles are made of Nalgene, not sure of CIS 
bottles but I suspect the same (they looked it). The big design 
difference is that a CFS has a breather hole in the top. The CIS also 
has a hole, but a small tube is connected to it which makes a 180 
degree bend and points downward.. I've often wondered if this would be 
an advantage or not, but you'd have to remove other variables- put the 
bottles side by side, tighten lids about the same amount, put same 
amount of  NEW k ink in each, seal off the hole to the tubing...an 
interesting experiment if someone had some spare k ink and bottles.

I didn't have any CFS tubing to compare next to CIS tubing, but having 
had two CIS units in the past, when I ordered my first CFS, it seemed 
to me as if the tubing was different- not quite as flexible. I could 
be totally wrong on this. Someone with a CIS could easily buy a foot 
or two of the CFS tubing cheap from MIS if they wanted to 
confirm/disprove this. Or if someone wants to send me a snippet of CIS 
tubing I can compare it to my old CFS sitting here- since I have 
calipers and a micrometer I can probably nail down even a small 
difference in outer or inner diameter which would be a giveaway that 
tubing was the same or different.
