I have two full-length open-shoulder fastskins that I bought just before Tempe. One is a medium (40) and the other is a medium-long (also 40). I've worn each only once to test. They're both very fast but as a distance swimmer I felt constricted in the chest. I had Speedo size me at nationals and they recommended the medium. I'd like to sell one or both for around $180 each. They retail for $240 so it's a great bargain. You can email me at tbryan@umich.edu.
