I'm late to the party but I would like to thow in my $.02 Coming from sportbikes, I rode damperless for several years before finally putting one on my 600RR (ohlins bar-type). After discovering the huge difference it made in cornering stability, I immediately turned around put on on the heavier 1KRR which up until that point, I thought was plenty stable through corners; it got even better. I rode the R1200GS for about a year before looking for a damper, mostly because nothing was readily available and the bike felt stable enough. I ended up going with Gavin/Mort's mount and a Scott's rotary damper. WOW what a difference! The twitchiness of the bike on dirt/gravel roads and it's new-found stability in sand are like night and day. I just got back from a multi-state trip through the Southwest and did some sand in and out of Chaco Canyon and you could feel the difference between just a few clicks of firmness on the damper when riding through sand and over washboard roads. On the road I found the fully rear-loaded bike was twichy in corners at times, especially on the tar-snakes. I had been running the damper pretty soft on the road, but after a couple moments in Utah, I ended up riding with the damper just a few clicks away from full-damping and the rest of the ride back to WA was stress free. My only criticism regarding the Hyperpro is the fact that it is not handlebar mounted; meaning you can't adjust it on the fly. So if you're say riding down a dirt road and you sense that some sand is coming up, you can't just crank up the hardness without stopping, or conversely if you need increased low-speed manuverability you can't reduce it easily either.
