My organization is very practical. The big benefit I see is avoiding lost discs. I have used two primary types of bags in my relatively short career.
1) One column of discs (Innova Deluxe, around 16 discs)
- generally organized by speed (putters-mids-fairways-drivers, and loosely by overstability within each group)
2) Different pockets (Upper Park Shift, my current bag, about 18 discs)
- This is my favorite setup. There are a total of 7 pockets (2 stretchy pockets on each side which are perfect for mids and putters, and 3 central pockets that each hold ~3 fairways/drivers). Since there are 7 total pockets, each with 2-4 discs, each disc ends up having a regular spot in my bag, so I have a very easy time checking to see if all discs are present and accounted for. There is one pocket that is just a hair more difficult to access, so I tend to keep less used or specialty discs in that spot.
- I can see this being a little less versatile than some bags, but it's perfect for me.
3) Large plastic bag or reusable grocery bag
- Suboptimal, but cheap and great for beginners. Difficult to organize, so my strategy is to decrease number in the bag. This also decreases the risk of possibly stretch tears in the plastic bags.
- I mainly used this strategy in my early days. In particular, I was hoping to get a sponsorship from someone like "Raisin' Canes" or even "Ross" or another department store. Unfortunately, I didn't have any luck. Also, as my bag expanded I decided it wasn't worth suffering through the organization difficulties.
- I do use this strategy on some vacations, usually with up to 5-7 discs.
