I have one of them there Innova bags that can be divided into three compartments. Here's how mine plays out:
Putter pocket (putters): Ion and Anode
Left compartment (slow speed): Pure x2, Fuse, Buzzz, Pain
Center compartment (fairways): Gazelle, Leopard, River, Teebird, TL
Right compartment (drivers): Saint, Predator, Avenger SS, Beast, Firebird
The right compartment changes just about weekly. I tend to always have the Saint, Avenger, and an overstable driver in there, but the rest gets shuffled through depending on my mood or how long it's been since I threw a certain disc. I almost never switch out my fairways, mids, or putters because those are the discs I throw the most.
