It's too easy to get on the plane with a large rucksack on your back (even containing a take-apart paddle). Some people I knew had to go by car, so that they could take their rigid SUP boards...
What's more, I can take the metro. It's really very convenient.
For this journey, I have chosen the 40-140 liter convertible bag, so that I can carry my inflatable stand-up paddle board, my paddle and my pump in the big compartment. In the small, watertight compartment, I put all my things for the weekend. This also gives me a comfortable rucksack for getting around Paris.
