This will be good entertainment. Most including myself will say that there is little to zero difference when using one. And that is not meant to take anything away from jetworks at all, because they are geniuses in the industry and build some wicked finger breaking machines. (sorry Matt)
Anyways, I would save my money for something else. I have an adjustable blue one that I pulled off my ski that I will ship to you for $25 if interested, but... Save your cash.
