Look at it from the bright side, Atleast you got in writing that you're allowed to take tanks, as long as the're empty.
Funny that in the same (medium) size/weight bracket, you pay twice as much for a bike as for your kite.
And you pay 3 times as much for your your fishing stuff as for (water) ski gear.
There must be a logic to this, but I'm buggered if I see it.
