I agree with Greg here, there’s so much cross-mod interaction that even just trying to wriggle in a handful of big mods is going to take you months, if not years. I speak by experience, because I’ve been scripting my pack for the past year and a half. Your best bet is, as always, doing it yourself. Gregtech (and MTutils) give you all the tools to do what you want, all you really need to add is a lot of time, trial and error and frustration.
On that regard, if I may go offtopic just a smidge, I’d like to ask Greg a question: How come GT pyrotheum dust cannot be used to smelt items/be used in a burning box? Is it a balance thing or does it just have its burning time when TE is installed?
