Digital BW, The Print

How do you like those Cave Paint inks? 

Any clogging?

 Are you refilling carts with them or using a CFS?

I am quite interested in how the color gamut compares to UltraChrome as well as  how the 
monochome prints look in regard to metamerism?

I may condider the Cave Paint for my 10K printer down the road?
