Thanks to the new Fina rules...apparently you aren't able to use suits with special patterns or any kind of 3d suit scales.
So does that mean the FS-Pro is slower than the FS-II? Seems as if the FS-Pro was rushed considering the spacing between Fastskin-I and II's release.
What about the other branded non-patterned suits such as the Nike hydra or the Arena Powerskin? I would think that would just be like wearing a full body practice jammer, not so light moving through the water.
And the biggest question. which one should last longer?
