Re: [Paddlewise] Back-up? (was: Rough Water Rescue and Foot Pumps)

Hi Dan,

Have you (or anyone else on this list) ever used one of these devices in a
real situation? I think it is based on a good concept, since rolling back
up, whichever way, beats a wet-exit and self-rescue hands down.  However I
doubt I will ever have the opportunity to try one myself. Also, what are
the chances of loading it improperly such that it fails to deploy?

On a lighter note, I bet this would be a good backup device for
practicing one of the most impressive rolls imaginable... The Straight
Jacket Roll. But only if it can be deployed with yer teeth :)
