Ended up with Park Tools link pliers. They are at least one plier instead of two different ones for the job of opening and closing like the KMX ones!
Carried them in the pack for a bit, but still too big and I’m trying to get it down to the point of not using a backpack at all for short rides.
On the trail, if the chain snaps, chain tool to break offending link off (mini tool kit), and then use the force (or pedals at least) to click the new link into place.
Other than that I’d be using the pliers for times I actually need to remove the chain. Noting I got it for 10/11sp KMC as they’re much more of a git to remove by hand.
