I would say its high time for the SSDT rule committee to accept a standard & safe 'bottle' for riders to carry around - so they are not ridung against the rules.
C'mon SSDT time for a minor tweak to the rules here and at the same time ensure safety.
Me were I to ride again a bottle & Hebo tank would be a must ! (As you never know if you will need it or not)

they do let you carry fuel in a hebo fuel tank
