I've been riding a Cannondale Synapse Carbon 2 for a little over a year now, and I'm happy as the proverbial pig in poo. My initial concern when I first bought the bike (that it wasn't quite as responsive for quick left/right transitions as a more "twitchy" race-oriented geometry might be) has proven to be a non-issue; I've just never encountered a real world situation where I had to force the bike to do a quick side-to-side evasive action and it couldn't keep up. The only other negative I can find is that when I'm really mashing the heck out of a (too-)big gear uphill, there's some frame flex @ the bottom bracket that causes the FD to rub. But every other <$5000 bike I've ridden does this too.
Other than that, the Synapse rides like a dream. Or, more to the point, it rides like a hovercraft: floating on a cushion of air, able to accelerate seemingly instantaneously & effortlessly, goes fast, feels comfortable, won't kill your children... I like it.
