Thanks for sharing these.
Flint Craft is very cool, I like that alot but with all the extra gadgets and tools in Mindcrack I doubt it would get much use passed the early stages of starting out. Definetely going to try that in SP survival though. Be great in hardcore mode.
I also like Clean Weather and enhanced visuals, although I can see myself getting a little annoyed with Enhanced Visuals once I've seen them all a few times or in the heat of battle when theres alot going on.
I enjoy immersive mods and visuals aslong as they dont distract or detract from the usual minecrafty-ness too much.
