I don't really like using APS, because I view MJ as pneumatic energy. This means it must come from some sort of engine. On the other hand, EU is electricity in my view. (I also can't get APS to work without making assembly table recipes screwed up.
Wireless Redstone is in Technic. Portal Gun really shouldn't need a retex, but some large mods (ahem, Vanilla with Sprinkles) could use texturing, assuming they don't already base off the texture pack.
