Hmm NG kits. I pre-ordered 1988 1/144 Zeta Plus and Full Armor ZZ. From the reviews they definitely needs lots of sanding to get rid of the rounded edges, and sanding is my worse skill…
Joints are ok mostly. Hip joint not so much. Even painted it’s still loose a bit. But other jounts from this line are fine. Not sure about the ZZ and Zeta lines though but given the scale is the same you should be ok.
