I hear people say that all the time. I bet 95% of the people who say it have read it, but never experienced it. When Hicas does its thing, 99% of the time you don't feel it. If you're pushing hard and you do feel it, just go with the flow, it's certainly not un-predictable if you understand what it is going to do..
Why remove all that tech and development in hopes that a solid bar will do a better job, especially if has never been a problem for you. Don't remove it just because you read something on a forum somewhere, some clever little Japanese men put a lot of thought and money into designing a system that does some really clever things to improve handling and driveability. If a solid bar was better, Nissan would have installed it in the factory...
Unless you're trying to reduce the weight in the car, and you never plan to drive around corners (eg drag car), or you plan to do loads of drifting, save yourself the $$ and learn to enjoy the hicas.
