To elaborate on what I like about the bag:
The size is right for me. I wanted a G-series but it just doesn't have the room for a hoodie, gloves, and extra water bottles for the kids.
It sits really nicely, I have my 6 go to discs in the 2 upper pockets. "Putter pocket" has a wiz, zone, And comet, and the other top pocket hasThunderbird, Valkyrie, and buzzz. All I keep in the bottom for discs is backups if I'm carrying them and utility stuff like a Stego and FB. So most of the time I'm setting it upright and grabbing a disc out of the top, which works great. It's comfortable and pretty light. The build quality seems as good as you're going to find for a mass-produced bag.
My only minor gripes are:
I use a 20 Oz thermos as my usual water bottle, and there's really no way to get it to fit tightly so if I bend past horizontal to say to pick up a disc, the thermos falls out.
Something about the strap geometry makes it feel really insecure when scrambling up and down rough terrain unless the chest strap is clipped, so I find myself clipping and unclipping a lot (our course is all rough terrain).
