One picture illustrates a "girdle-like" construct within the suit to keep your core tighter. Now, if FINA can let THAT be okay, then why not "tripwires" on the Aquashift? Lame!
The Lazr costs $550; the jammers are $290. It's unfortunate that no swimming publication; albeit online or in print, have the courage to test these types of suits in a side-by-side comparison to see which brand really offers the fastest suit technology or even what sort of time advantage does one offer over the others. What if the Speedo Lazr is the fastest suit in the world but only offers a 2-tenths-of-a-second improvement in a 100 LCM free? Is the suit worth $500 to you if it makes you look like a "trekkie." Also, highly paid "mercenaries" do not count. Michale Phelps could probably with a 200 fly wearing wool board shorts.
Car and Driver has their "Car of the Year" and they certainly do shootouts from time to time.
