I had the opportunity to try this handle for a set last week at Okeeheelee. Paul Turner had one and was offering to let a few people use it. Although I think the handle is a great innovation, and may work for some people, I will be sticking with a regular handle. The biggest problem is that you need to grip the handle right at the center. If your hand grips even an inch or two away from the center, there is the very real feeling of your hand wanting to slip off. Because of this, there is no flexibility on where you place your hand on the handle.
With a regular handle, there is a bit of play with where you grip and if you grip near the end of the handle, your hand won’t slip off. But with this handle, you have to get your hand in the same exact spot every single time and I found it distracting to have to think about that. I saw some talk of putting a nub at the ends of the handle, and I actually think it could be helpful. Also, the material on the handle feels slightly more slippery than the material on a regular handle.
I saw a lot of chatter about how this handle would affect your technique. I personally didn’t feel it change anything about the way I ski for better or for worse. I don’t see it having a drastic effect on the way a person skis.
