Digital BW, The Print

I am currently using Permajet VT Blax inks (rebranded MIS mono inks) 
and am looking at a CIS; either the Lyson system (small gamut) or the 
Permaflow VT Blax(MIS rebranded).

What I am looking for is some comparisons between the 2 such clogging 
experiences and quality of the final image.  I have been fairly 
pleased with the VT balx apart from when I take the cartridge out it 
introduces an air block which I cannot shift.

Thanks

Gareth
