Can i use IC2 for Minecraft 1.6.4 on my Minecraft 1.7.2 server?

  • I have setup a Minecraft 1.7.2 server since most mods and plugins have been updated at least that far. I realized too late that my favorite mod, IC2 (can't play Minecraft without it) is only an experimental build for 1.7.2. So hence my question, Is there a non-experimental IC2 1.6.4 and if so, can I just use it on my 1.7.2 server so I am not plagued with game/world breaking bugs?

    Also, is the latest 1.7.2 IC2 build stable/playable enough? It has not had any updates for 22 days so far. I really need IC2!
