Lots of rough crap. I’ve never had a bottle pop out, and plenty easy to pull a bottle when needed. Easy and secure.
I'm going to try the Zefal Magnum too. When I tried a Specialized Purist, it didn't fit well (too big) and was ~ 24 cm outside circumference.

Note that the main reason the Polar bottle works well with the King cage is that the 'waist' is perfectly positioned for the cage. When the bottle is put in, it sort of snaps in place. Since a Kleen Kanteen doesn't have this waist/narrow section, I think it's going to be problematic, or at least kind of tight.
Cool, King Cage recommends the 27 oz Klean Kanteen as well as a 16 oz (Klean Kanteen I am guessing). I have a 27 oz Klean Kanteen which fits perfectly due to it being ~ 23 cm outside circumference and rigid enough to spread the Iris cage just a bit -- but it's a poor water bottle choice in the heat. Bigger 24 cm + circumference plastic bottles kind of just get munged and deformed.
I noted a review on Amazon of the Polar Bottle griping about its narrow waist, I think because it prevented putting more ice in, though I took this to be a possible benefit as you say. I'm guessing the waist is helpful for fit of the Polar into the Iris, but bet the smaller outside circumference of ~ 23 cm (or 74 mm diameter as you measured) is as important.
