I want to take up your offer on DS track moaning:
A: It's crap
B: No it's convenient!
A: It doesn't sag!
B: It sags if you know how to do it
A: It melts!
B: That's old news
A: Friul looks much better!
B: But it's expensive
Anything I missed?

I'm doing metal tracks so it doesn't matter for me.
On the kit itself, the ausf A (6860) is a problematic kit and this B shares 99% of the parts. It's just too many versions away from the original G they based on. The superstructure has some serious fitting issues that I discovered too late, and the breech stuck out too much. The instructions didn't help as usual, but compounded by the fact that they piled on too many changes to get from G to A.
ps. This News item disappeared for a day... thought something happened to the release....
