Yeah, I'm never thrilled to get a bunch of tiny bits of metal. Plastic isn't so bad, as it glues easier. I'm looking forward to seeing them switch over to the new plastic, although there're still all the issues of Chinese manufacturing...blech.
I use the greenstuff method (a light sheen of glue, a tiny dab of greenstuff - well, PP's version, but whatevers - and a light sheen of glue on the other piece). It seemed to work well. While there are a ton of bits, the mold quality was very good - better than most PP stuff - and they fit nicely, most into formed grooves with lots of surface area. I believe I pinned the upper hand on each guard's axe, and Zerkova's arm absolutely needs serious pinning. I don't think anything else is really required unless durability is really an issue.
I assemble pretty much everything before painting. My skill is humble anyways, and I firmly ascribe to the notion that if you can't get a paintbrush in there, nobody cares/that's what ink is for.
I look forward to seeing them! I haven't done much of anything lately - more invested in writing. And my next step is to magnetize a bunch of Everblight heavies, which is going to be a pain.
