I haven't seen anyone using it. I've tried it a few times for giggles on fun night. Felt very uncomfortable, but was able to rip off a nice string of strikes doing it. I always wonder what it would do to ones spare pick up having to switch styles so drastically. Seems like there are a lot variables built into it, with having to get both hands to do things at the exact same time every time. Of course if I hyperextend my fingers a couple more times I might have to go to it, lol.
