I rode my bike for the first 2 or three months without one. Then found a great deal on one and installed it. The nice thing about scotts is that you only need to buy the mounting bracket for all your bike's, then you can swap the Damper back and forth to what ever bike your riding.
I ride my bike like I stole it (within my ability of course) and could tell the difference with the damper. I like it, gives me a little security, and it plain ole works.
However, I completely understand Stig's point too. Seems like his bike is set up to the extreme, to turn fast, so I see how the damper could hinder that.
