After running a few tests with different mod packs i've arrived at the one it think will be best. I'ts massive in content ( yes more than FTB and the 1.7.10 pack)
Link to modpack:
https://minecraft.curseforge.com/projects/all-the-mods-3
INSTRUCTIONS:
1. Download the modpack using the client on the website ( curse forge)
2. Find " all the mods 3" via the client
3. Install
4. In the modpack launcher, be sure to go to profile options and uncheck " system settings" at MEMORY SETTINGS. Put this as high as you can to ensure a smooth experience ingame)
