I use the absolute dry on my road bikes. Gold on my mountain bikes, which need the help with shifting (old XT, as opposed to Dura-Ace on my road bikes).
IMHO, it's the best stuff out there. I'd be shocked if you didn't love it. It does everything they say. Quiets the drivetrain and improves shifting. I find that it's easier to keep the drivetrain clean as well. The dry picks up less debris overall and the gold cleans and lubes as you apply it.
It's the cleanest stuff I've ever used. Be certain that once you switch to it that you use ONLY R&R...if you put anything else on top of it you'll end up with a black goopy mess that will need to be cleaned off.
It's also good to use on clipless pedals to keep the interface surface nice and slick for easy entry/exit and to eliminate those annoying cleat squeaks.
A friend of mine recommended it to me and I love it--it cleans and lubes all in one. Works great. I mainly do mountain biking now though. It helps keep my drivetrain clean as it doesn't attract as much dust/dirt.
