Go with Finis!!! The VAPOR is the most sophisticated suit out there! Anthony Ervin wears it in the "MINT" color; super cool, but super fast!!! You can use my promo code of Lrace14 to save 10%!!!
Or get a Yingfa for a fraction of the cost of those ridiculously overpriced suits. I just got one for $30 and I seriously doubt it is significantly slower than the $350 suits out there.
With body suits there was a significant difference between suits. Jammers, not so much.
