Travelling with carbon fins. Best bags/storage?

I think I responded to a recent thread about this, but anyway..

Basically you need to get a luggage thats long enough to fit your fins. Cressi makes a big bag for this, but I prefer using my +90L hiking pack because it has an obvious up/down orientation (foot pockets go up). For the fins them selves, they go in a sheath made of folded 3-5mm corrugated plastic and taped in place with electric or duct tape.. This goes in the centre of your bag surrounded by all of your soft things like wetsuits, towels, and clothes.

In any case I've check-luggaged fins in the hiking pack 4 times, and when I came to Dahab in January I had 3 pairs of fins in the Cressi bag. 2 pairs were carbon and 1 of the carbon pairs wasn't put in a plastic sheath..

I think as long as the fins don't touch the wall of what ever you are putting them in they can handle quite a bit.. If you compare with how much they bend under water then a bag being tossed on top doesn't seem so bad, as long as you protect them from impacts with your t-shirts.

I usually put mine in my sporttube with my guns in a neoprene cover to prevent scratches.

When I travel, I take my old fiberglass blades. They're tougher. I did take carbon fins once. I carried them on board and asked the flight attendant to keep them with the coats. It was not a problem.
