You need to read a bit deeper, dude. Composer's Collection is still regular, full price.
The 67% off you're reading is off each individual item. It's ALWAYS 67% off, that's the point of the bundle.
Don't get Voices of Passion, Goliath, or Ministry of Rock. Voices of Passion is a niche vocal library, Ministry of Rock guitars suck, and
(and why get a smorgasbord within a giant smorgasbord bundle? That's redundant.). Goliath has a lot of orchestral, ethnic, and band/synth sounds. You're going to use Symphonic Orchestra for the orchestral and Ra/Other stuff for the ethnic. If you want to avoid redundancy, don't go Goliath.Here's what I would do for least redundancy and most ground covered, as far as cinematics:
Symphonic Orchestra Gold
Pianos Gold
Symphonic Choirs Bundle
Storm Drum 2 Bundle
Ra
Silk
Gypsy
This doesn't have band instruments, so you could swap out Pianos for Fab Four/Ministry of Rock if you really wanted.
Or you can just blow $1800 and get their whole collection, since they allow you to make it more than 7 instruments now.
