Thanks very much Paul.  I'll try your method of filling half way, 
clear the foam and then fill the rest.  Also I think a CFS will 
ultimately be the answer especially now that the UT2 ink is working 
out so well.  I was refilling trying to decide what ink I liked but I 
think I found it.

Again, thanks for your time and your knowledge that you so graciously 
share with us.
