In case the video wasn't watchable:
I got a new Ergo 3 disc golf bag from Big Hyzer Bags (
www.bighyzerbags.com). I have had an Ergo 2 for a year... I like the Ergo 3 more. It's more comfortable and holds more discs.
With 23 discs and a full water bottle, the bag did not feel heavy at all. It was extremely comfortable using one strap or two.
It's a sturdy bag. Even though it's a bit taller than others, it doesn't seem to be at risk of falling over. The frame is strong but doesn't get in the way of anything (side pockets or inside disc storage).
The handle is comfortable to hold and easy to use. It's definitely an upgrade from the Ergo 2.
The built-in seat is okay, but not great for long-term sitting.
The side pockets are about the same as the old Ergo 2 bag: big enough to put a few towels and snacks, but not practical for packing away a sweatshirt or something very large.
I wish it had a pencil pocket or two.
The front putter pocket is okay... it holds three putters easily and doesn't get in the way if you stack your discs vertically.
There's a storage area at the top (under the seat) that is okay. It's big enough to put away lots of little things (sunglasses, keys, etc), but the access point (zipper) creates a risk of letting things fall out a bit when you open it. I loved the top pocket on the Ergo 2... the one one the Ergo 3 is just as big (or bigger), but relatively harder to use.
I love the D-ring at the top to hang towels and bag tags. The fact that it's so high is a plus for me. On the Ergo 2, I clipped my towel to a zipper pull on the top pocket just so it wouldn't drag on the ground.
Overall, this bag is a good upgrade over the Ergo 2. I really like this bag even with its small shortfalls.
