I appreciate the innovation, and would be interested in trying the handle.
However, as skier who broke his arm with a conventional handle putting me out of skiing for a season, and out of tennis for two years, I am uncertain about the tradeoff in risks with the traditional bridle versus your new concept.
To be brief, when a skier falls, and his head or a hand goes into the water ahead of your handle, either end of the handle could do damage when it catches up to the skiers neck or arm. I am not certain the handle would spin away from your neck or arm fast enough to avoid injury.
On the other hand, in certain falls, the two legs of the triangle on a conventional bridle can act as a guardrail to move the handle away from the neck or arm unless the neck or arm went inside the triangle as happened when I broke my arm.
I don't like being a sceptic, but I wouldn't be comfortable being in the water when the open ended handle is being pulled past my hear, neck or arm.
I believe there is a tradeoff of risks here and I am not sure which arrangement is safer. Has the bridle with the mesh been discussed here ? Isn't that the safest option ?
