Sunny on the Modded Side+ is a compilation of some of the best and most essential mods that I could think of. This pack was made with compatibility in mind so I have edited some of the configs to disable ore spawns from IC2 to allow CoFH core to spawn most of the mods needed. I have also disabled MineFactory Reloaded's rubber trees as IC2's work just the same but you can change that of course.
This pack was designed to have a feel of familiarity with already experienced modders and to also be friendly to those just starting to get into modding.
