Digital BW, The Print

Hello,

apologies for my english ... hope you will understand me !

I would like to mix inks myself (C6 inkset on epson 1400). I use most of the time Arches uncoated paper and I've read Paul's PDF talking about C6C base. One sentence sounds disturbing to me : "As the newest of the base variations, this mix may have involve more uncertainty." 

Any further information about that ? No problem so far to use it on fine art prints that could be sold ?

In this approach, would you advise me instead to use C6B just "to be sure" ?

Last question : what tools are needed to make dilutions ? graduated pipettes ?

Thank you very much.
