For what it's worth, I carry 22 discs in my grip a-series bag. The side pockets are a little too small for my liking. I'd like to be able to fit an Xl size jacket but I can't. But I can fit an extra water bottle (3 total in the whole bag), two minis, a 12inx12in towel, book of score cards, sharpies, and extra socks in there comfortably. I've only been using this bag for about a month. The only complaint with it is how the straps are susceptible to loosening when putting my second arm through. I wear the bag high on my back, so when I stick my arm through, it loosens the strap. As for sturdiness, I can't say that this bag will never tip over. In fact, on my hilly home course, it tips over probably once or twice a round. I haven't had the opportunity to try any of the other bags listed, but compared to my old fade tourney bag (which I loved a lot) this bag is far superior. I'd definitely recommend it. The many pros definitely outweigh the few cons.
