I went for balanced.
Version 0 is a big no to me. Compressing the main page into 3 subforums makes the entire forum look so small it's barely worth visiting when looking at the main page alone, and that's kind of depressing.
Hyper is better, but still slightly too compressed for my liking.
Balanced is my favorite, since it keeps the main page more appealing and less like some dying forum kept as an archive thanks to the subsections still existing. To be honest, even hyper is slightly depressing to look at for me, even though I realise we don't really need a lot of subforums for our amount of activity.
Rule of existence: Whenever luck is involved, somehow, somewhere, someone will get trolled by it.
