Getting back into swimming more seriously, been years since I wore skins and wondering how much of a difference they make?
I've heard people talking in the region of a second/100 which is pretty big.

Have currently been racing in speedo endurance jammers and see everyone at galas with arena carbon pros (£190 pricey! Sorry for the UK centrism there). See cheaper versions like the arena powerskin ST 2 for £50, is there a big differential in performance between cheap and expensive tech suits?

Any thoughts much appreciated :)
