I'm interested to see if the Schwalbe alternative is any better. Good to see that they can be patched with regular park patches too.

Yep. You're not supposed to inflate tubes outside tyres.
A little bit of pressure to give them a bit of shape when you install but not so much they look like @clockwork_killa pic. If that pressure gauge is accurate though, it doesn't bode well for Tubolitos
latex tubes used to do that but they work absolutely fine even if they bulge like that outside the tyre
