Great bottles, love the higher capacity. They definitely have a faster / higher volume flow per squeeze which makes it much easier to grab a quick drink. I like the clear bottles so I can easily see how much I have in there. The caps can be a tiny bit leaky. A few drops here and there are irrelevant outside, but can add up during longer indoor rides. I'll certainly take light-weight over unnecessary extra weight, but the weight of the bottle is a pretty minor factor when you consider you'll have almost a whole kg of fluid in one.
I got the brushed stainless insulated version. You definitely lose a little bit of capacity for the insulation.
My Arundel Mandible carbon cages hold them very securely on my gravel bike over rough technical sections. Not one bottle eject after hundreds of gravel miles. The stainless is abraded a bit by dirt and the cages but they still look great to me.
Great flow. Like seriously great. If the flow seems slow, and the bottle has water in it, pull the nozzle a little with your teeth while riding to make sure it's open.
I'm a candy fiend already, so something like a sport nutrition snack made by Jelly Belly was a no-brainer. These are tart, have great flavor, don't get all melty or warm, don't get all sticky, and come in a resealable bag, that you could even repurpose for a tiny trash pouch for unexpected messes or tissues. The 50mg of caffeine per bag is the perfect amount, and they're easy to eat while on the bike or stopped. My favorite ride fuel snack/chew, by far.
