When I started, the most advanced suit was he nylon brief. Clearly the "shiny suits" were faster, but they covered your whole body. Jammers cover such a smaller area I have to wonder how much difference the top of the line ones make vs more affordable. Has anyone done testing or any objective measure? Shaving down makes about 1 second/100 difference for me and every .01 sec can be important, but is there even .01 sec difference between good jammers and top of the line?
