I had been using the Pro Discover Medium bar and found the flare where the brake levers attach caused them to rotate inwards vertically, and my hands were resting on the outside angled edge of the 105 brake hoods and was quite uncomfortable. On these bars, the real flare begins below the brake lever attachment points and so the hood placement feels much more like a regular road bar and the difference in comfort is huge, for me at least. Taking off 2 stars because the markings are off, so takes much more effort to set it up properly.
Not the lightest wheels you can get at this price. Not the cheapest you can get a wheelset of this weight. However, the Zipp 30 Course is arguably one of the highest quality and best values. The wheels rim width offers versatility for a wide range of tires for road, cross, and gravel. The 30mm rim depth offers some aero benefit while limiting the effect of cross winds. They're well designed, built, and strong (compare the max PSI and rider weight limit) and per the specs are even a bit lighter than the Zipp 302 Carbon wheels.
All I can say is good things about this handlebar. Feels great in the drops and grips good on flat top for climbs. Paired with the Zipp Service Course SL Stem... you can't go wrong. Didn't notice any flexing. Atheistically... Beyond Black looks killer!
