I love the look of pipes. So I use AE for storage instead of transportation. Things come in and go out with pipes, instead of AE Cables. One of the reasons I still use Logistics Pipes. And if not that, then mine carts. Love to see them puttering around doing things. Makes the base really feel alive.
Minecarts are cool, I haven't done them though because they take up too much room. Although they'd be an interesting project for going down into a mine delivering some charcoal.
I've updated the world download link in case anyone's interested in what the project actually looks like, I've been playing around with gold conductive pipes and just tidied things up in general.
