Currently I use Ender IO cable and Mek Universal power cable, but I am sorely missing TE's item/fluiduct in early game play. The Ender IO item cable is tough to make in the beginning, and the XU cables I use early on work well enough but don't look as nice as the old TE ducts.
What I'm *really* hoping for is something that adds more logistics pipes functionality without the buildcraft look. Being able to keep, say, 64 oak saplings in my planter or some such just using a config setting. The stuffing and buffering craziness in Agrarian Skies forced me to run all my farms using AE, which was.. not precisely ideal.
I also loved the look of the old TE conduit. I hope it doesn't change much.
