For a cut too big for a plug, as you say a tube is the answer, so hence why I questioned why nobody above included above a tire boot in their kit, but they do have tubes?
Interesting to also see one mention of bringing a pump and a plug, but no CO2. Presumably there are now combos for TL Tire/Rim where a TL tire can be seated with the relatively low volume minipump capabilities.
Sealant slows down the leak quite a bit, even if it doesn't seal it. For sealant to all be gone by the time you come to a stop, either the cut was way too large for you to have a prayer or you didn't have enough sealant in the first place.
I do carry a tube but don't have a dedicated boot; I always have a bill or a wrapper on hand.
CO2 might be handy for re-seating, but is generally not needed on the road. Many tires will stay seated even when completely flat and re-seating isn't a concern if you're going to pop in a tube.
