Rihac or piano book CISS

[Gunpowderboy]

I'm looking at getting a CISS for my brother DCP 770CW printer. I like the small footprint of the piano book system, but I cant seem to find any reviews of it online. On the otherhand the RIHAC system seems to have glowing reviews both as a system and for the inks.

Are there any differences between the systems that I dont know about except for the footprint?
