Yeah, that's my thinking. They're a last resort anyway. I'd hope to use dynaplug/anchovy for any normal holes and if I have to take the tyre off because of a sidewall cut or whatever then I'd likely just grab a tube.
They'd need to be patchable in case the tyre boot lets go and I wonder how abrasion resistant they are, given they'll be spending a long time in a frame bag or whatever. At least is this funky material better or worse than butyl?
If they mostly work then all good, only need to get you as far as the next shop for another back up. I realise for you that might be a few hundred miles more than me but schwalbe claim they're better than butyl and as I'm basically not using them anyway that's enough for me.
