Digital BW, The Print

I am using a Epson 1.5pl Claria printer (r280-ish). I was thinking of using MIS PKs (like UT14 M or C) and diluting them with MIS glop for glossy only printing. Could I expect a quality difference between such inks and premixed dilutions from MIS (such as UT14 LM or LC)? By quality I am referring to ink flow, clogging, drying time, image clarity, etc.
