Ventus isn’t UCI-legal, Brezza is. Ventus has a rear tail that isnt compatible with frames that has cables entering the top tube close to the steerer tube(like the '11 P4) which can be an issue if you decide to change frames.
I would skip the Brezza II. It’s pretty wide(unaero). Also, the Ventus is bound to get cheaper as the 2012 3T line is about to come out.
I would either go with the Brezza 1 someone sent you a link to, or wait to see if the 2012 products get the previous generations to go on sale and go with the Ventus.

The Brezza and the Ventus are both offered in 40cm. I realize aerodynamic comparisons can’t be made on the basis of macro geometry alone, but your statement is pretty unfounded. Just saying…
I didn’t like the Brezza because I felt like I would snap the extensions off. I never actually rode them, but just from picking up the bars and getting in position on a demo bike that spec’d them the amount of flex they had was extremely disconcerting. I had a similar concern with the Aura.
I’ve heard about the brezza being more flexibile than the aura and other aero bars. A pro could be its more shock absorbing but what makes it more flexible than other aerobars? Shouldn’t all of them be made out of carbon?
I just sold my ventus and have to admit, the flex on it is pretty concerning. I’m talking about flex on the basebars. I rarely ride on em but when accelerating from a stop, it’s definitely worrisome to feel that amount of flex. Got the HED dropped blackdogs and I feel ALOT more secure. Otherwise though, I loved the ventus. Comfortable, sexy and obviously aero. Would have kept it and dealt with the flex if it was compatible with the P4
It was probably your stem or your steerer tube. I’m pretty sure it’s not possible to discern base bar flex from stem+steerer tube flex because you simply don’t have enough points of reference to determine what is moving and what isn’t. Flex that you attribute to the basebar is more than likely the steerer tube or stem deflecting under load. The base bar is stiff as shit, and if you try torquing the base bar by itself you’d see that as a mere mortal you probably can’t get it to bend a humanly detectable amount.
I have this same issue on my road bike, and while I initially thought it was my Zipp SLC2 drop bars that were bending whenever I cranked on them, but I started looking at things piece by piece and realized it wasn’t the bars after all.
I’m referring to the amount of flex in the extensions. To answer the OP’s question, no, carbon will not make the aerobars infinitely stiff. A small amount of play in the extension clamp (it’s not the best design), plus some extensions that were designed to be very lightweight inevitably means that some stiffness is sacrificed. The Brezza isn’t really any more or less stiff than the Aura from what I’ve heard from the guys at the LBS (they build up a couple bikes per week with the Aura, and a few with the Brezza). The Aura and Brezza both have a similar (if not identical) clamp mechanism, and the extensions are more or less the same. Get the bars in your hand, and give the extensions a squeeze at the end, or pull/push on just one or the other. Now imagine hitting some unseen road obstacle (pothole, crack, etc) while in the aero position. I couldn’t help but get a feeling that the extension was going to break every time…
