I can answer the portable tank one straight away - the rest comes down to personal choice.Really like all mods in this pack but lots of the stuff i really love is disabled on this pack. If this pack didn't change and disable so much and not tell you at all i may play it. The one that really gets me is the Portable Tank form Thermal Expansion seems like only the basic on is enabled and Agrocrafts ore plants are out then there also Quark in this pack but why bother adding Quark if you're just going to disable everything? if i could just enable everything again it would be nice
Higher tier tanks are not disabled - you now use Upgrade Kits to turn the basic tank into the more advanced ones - these have to be applied sequentially. Alternatively, Conversion Kits can be used to take an item straight to that tier. Note: its not just tanks that the upgrade kits work with, but most machines including dynamos.
