Well my main question is - should I begin now (way ahead of time) with making Scrap, and Scrap Boxes? If I'm gonna need tons of scrap, I think I'd rather put the saplings to use there instead of making a minor amount of additional energy that I honestly really don't need (altho we always need more energy, I understand that concept but I also understand trying to balance processes and not throw materials at places that don't really need it). My main power source is now Nitro-Diesel thru the Large Diesel Engine (with Oxygen feed), steam still makes my bio-gas, and the bio-gas still runs some machines but all my HV multiblocks like the EBF and Distillation Towers/Cracking Unit runs off the Nitro now... and I've already got almost a full Bedrockium Drum of Nitro in reserve. Things are going swell so far.
I've never done UUmatter in this modpack, but I've done it plenty of times in "vanilla" IC2 modpacks. In those play-thrus, I've used more scrap than I could probably even count... trillions of cobblestones from multiple ExtraUtil cobblegens running at lightning speed. I've already learned all "stone" materials don't generate scrap in this modpack, so I'm wondering if I should be looking for opportunities to take otherwise "worthless" stuff and begin with making Scrap?
