Michael Phelps swims without his new 'Speedo Lazr' at the 'Missouri Grand Prix'

Michael Phelps swims a 1:55.26 in the 200 fly at the Missouri Grand Prix sans a Speedo Lazr. I wonder if the other swimmers like Dara Torres, Katie Hoff, Kate Ziegler swam without the Lazr as well. You would think that they would have worn one since Speedo has been showboating it all over creation.
