I didn't want to jack the broken handle thread, so posted as continued discussion here.
It was noted that ARS handles don't do anything because you grab the handle with both hands opposing each other.
I use to think sonar well, until I started using them.
The benefit I feel is that the handle does not roll when you have just one hand on it and you return your other hand to grab.
It isn't that noticeable until you ski with them and then try to use a standard handle. I have done this when I forget my handle or trying a new handle (as the ARS radius is getting harder to find). There is a slight straightening out of the handle in my hand when I use regular handles and it just messes with your concentration, sort of like when you pull out of the water and the loop slips on the pylon.
Is it a big deal? No. But there is a difference.
