Do the majority of you ride 20 speeds?

Yes, but as my question noted, I was looking to compare DA 9 speed gruppo weights, 7700 stuff, with DA 10 speed gruppo weights, 7800 stuff, and the older DA 7700 stuff is no longer listed on the Shimano website, only the current offerings. Nonetheless, I got the information from various sources, and the aggregate weight savings for 10 speed 7800 DA compared to 9 speed 7700 DA for the 8 piece gruppo that I listed above is roughly a whopping 70 grams. The aggregate weight savings for 10 speed 6600 Ultegra compared to 9 speed 6500 Ultegra for the 8 piece gruppo that I listed above is roughly 102 grams.

Obviously these insignificant weight savings would not be a reason to upgrade from 9 to 10. I guess other reasons might be stiffer crank and bottom bracket, one more sprocket on the cassette and possibly slightly smoother shifting, none of which sound compelling enough to me to make me want to upgrade. Are there any other possible reasons to upgrade that I missed? For me personally, I probably won't be using 20 speed until such time I am in the market for an entire new bike, probably a couple of more years from now.

I ride Ultegra 9 on my newest rig, 2001 Trek 5200. I also run some ancient 6 speed stuff on my late 80s Schwinn Traveler. I mostly just commute on it, and it was what I trained on before I got a real bike. Ironically other than smoother shifting, lower bars, better ride, and lighter weight for better climbs, I am not much faster on it. I will probably upgrade to SRAM Force eventually. I love the double tap, and it weighs less than anything else out there until the Red comes out. I also prefer the hidden shifter cables too. For now the Ultegra 9 works great, and is gonna see it's first race on Saturday. I have ridden new Ultegra, Rival, and Force, they all work as good as the Ultegra I have now. I actually can't tell the difference other than the extra gear when it came to the Ultegra. I rode a 2008 Madone 5.2 with the Ultegra Compact, and it worked great, but I ran out of gear easy.

Well, I guess I'm still old school. I still ride my Malliard Helico-matic, 7 speed 26-12 (precursor of the current cassette) a Sun-Tour derailurer (front and rear) and a 42-52 Nervar crankset/chainrings.

Of course It's on a steel Pinarello frame from 1977!

(those on the fourm who raced at the Road Nationals @ Seven Springs saw it. I was the reporter bombing around on that old beast)

Having missed a few generations of tech, I'm kind of new to the whole Ti/Carbon fiber/ brakehoodshifting world. In a way, I prefer the Old School of downtube friction shifters and steel frames that I can fix myself....

I do.

What is 17.5 in KG (unless that is kgs, then yes your bike is very heavy!!!), we are all new fangled over here in OZ, 20 speed, kilograms, what's next????
