Speed Lzr Vs Speedo Aquablade

[California Dolphin]

I've never understood the rational for tech suits in competetive swimming.

Tech suits are just another form of mechanical swimming aid and using them in competetion is sort of a "cheat sheet" approach and nothing is really achieved by setting a new world record by using one.

I've often pointed out that FINA prohibits the use of other mechanical aids such as paddles and flippers and some exotic things like rubbing surfactants all over your body to break surface tension.

In the past, FINA preferred the racer briefs because they minimized the role of the suit and eliminated extraneous variables as much as possible. So why has FINA done a 180 degree turn and allowed "suit technology", but not other devices?
