Somebody needs to make a release that is designed in such a way so as not to release completely or should I say, it does not release instantaneously. Let's say the maximum tension a pro skier puts on the rope is somewhere around 800lb (BTW, I have no knowledge of how much they actually put on a rope)
Take a ski run, and theoretically put over 800 LBS on the line(because you held onto a slack hit), the release triggers, but simply let's out extra line until the tension on the rope drops to zero. This way, nobody whacks the handle into their temple or ribcage AND if an appendage had been caught within the bridle perhaps the damage could be lessened.
I'm willing to believe a good group of engineers could design such a system to accommodate two types of falls. Maybe the rope could have a very fast intial release, (for arm through the handle falls) and then a higher tension/slower "second stage" release (for slack hits and the like). Of course nothing is going to save anyone from an actual broken rope/handle.
I realize I am nobody in the slalom world but I really like my idea. I'm not going to stand by it and say its the only way, but I think there has to be a device that takes more human error out of the equation and operates without human intervention... but... Perhaps this release I've described could also have a manual override where an observer in the boat could decide to release the line completely just like tricks.
What do you all say? I think there is a lot of room for reasonableness in a new design.
