Why do you disable Wireless Redstone and Additional Pipes? Is it because of griefing uses or server performance? Maybe in your post you specify the reasoning.
I run a server for my friends and I. I'm more concerned about performance issues in mods than griefing.
I also prefer Residence over Towny like you. Found Towny to be a pain because it protects everything even the wild. Residence only protects things people want to protect.
