I think that before we choose the right wetsuit we need to consider which one will suit our technique best.
for instance, IMHO Orca suits (Free or Breathe) are better in DNF than B70 Nero. However this only apply for people who are swimming with slow-normal pace. In my case with Orca or full Elios 1,5mm I can go down to 2-2,5 strokes per length. In B70 Nero it's very difficult, usually I do 3-3,5 strokes.
Things change when You swim like F. Sessa or D. Zoretic. I mean for people who tends to swim faster and smoother, fastkins are better.
