Another vote for ClassicWB..
I run ClassicWB Full on my 1200...
Started with it when I only had an 8M FAST RAM card and loved it.
Works even smoother with my ACA1230/28.
My only real "add" that it didn't have was a DOCK.
But then I found ToolManager..
Works great..
I run it in Interlace mode (did when I had it on a 1084 too, but use MagicTV to reduce the flicker), as I like smaller icons. ;-)
I've considered 3.5/3.9, but I like my current setup right now, so not as much motivation to really try them out...
