I wouldn't recommend the Extra Light unless you are willing to carry multiple spare tubes. 8 or 10 per day would probably be a safe number. I had 4 blowouts - not flats but explosions

- at 90 psi in the same width on a loaded touring bike and only one person. I eventually got the bike to stop having blowouts by lowering the pressure to around 70 psi.
Keep looking.
