Minor nitpick/suggestion: since amassing a huge amount of resources is a big (if not the biggest) part of this modpack, (to me) ore doubling becomes essential (at least in the early-to-mid game). That being said, could you remove the Auto Smelt from the list of random upgrades from Iguana Tinker Tweaks? I had the unpleasant surprise of receiving that on my decently-leveled pick the other day and it became slightly useless because I LOVE ore doubling and even after I automate stuff, I still like to go on manual mining trips. (haven't tried it on all ores, but it definitely smelts iron)
