It's a large-sized pack with currently around 240 mods that started out as a private pack for a few friends of mine.
It has all the basics that most packs include but with a nice mix of some of newer or lesser-known mods as well.
It includes Mekanism, Thaumcraft, Ender IO, Thermal Expansion for the big names and Rustic, Traverse and Bewitchment for the not as well known!
Server pack is available
