Hookless tubeless wheels typically weigh less. But the fact that tubeless setups weigh 200 grams less is irrelevant, half a pound has no meaningful impact on time
Zipp 303s weigh 1558g and IMO that isn't that light for a 45mm deep wheel. The EliteWheels Drive 50D I just got are not only cheaper but 50mm deep at 1290g. So even before we talk about tires, tubes, sealant, ect the Zipps are 268g heavier which is a good deal of weight at .6lbs. This is my hole issue with the Zipp 303S, they MSRP at $1400 which is indeed reasonable for a name brand wheel that is sold in LBS and has an amazing warranty, but let's say you don't want EliteWheels the Winspace D45 are 1420g which is still 138g, couple hundred cheaper, the wheels are more aero, and they come with ceramic bearings and carbon spokes. Too me the Zipp 303S are really nothing special unless you has a tendency to constantly RMA brake your wheels
