I haven't tried it yet but I dig the concept. I personally really love my UDi2 set up on my Ti road bike and cannot really see much improvement on that aside from allowing the software to allow MTB rear derailleurs to work with road front derailleurs on either shifters. The Wireless is a neat concept but charging a bunch of batteries plus having little cell batteries is just not my thing.

Hydraulic sounds like it could be pretty neat in providing really solid shifting with lower maintenance and I always love those who try and get into the market and come up with something new. I had been interested in trying the ACROS system back when it was available but never went for it and then it was sold out. Plus the idea of more gears on a 1x system is intriguing. If someone gave me a chance to try something with the Rotor system I would happily jump on it. Same thing with the FSA WE gruppo. I love Shimano but always love seeing companies trying to go up against the big guy. It helps drive innovation and provides unique opportunities to see something different because you have to find a way around patents and such so it requires creativitiy.
