For all your "purists" out there, you all have my permission to go swim in your wool suits and no goggles but allow that guy in the photo above to go swim in his CH2-CC1-CH_CH2 "Batman" suit!
Seriously, if speed suits make you more buoyant, then they should be banned across the board from age group swimming to the Olympics. However, if they don't and the material is solely about coefficient drag flow or how "slippery" the suit handles within the water, then suit companies should be unfettered and let loose to create suits that allow any swimmer reach their maximum potential.
