Personally, I love this suit. You feel a dramatic reduction in friction in the water. I have heard from a few and will agree to a certain extent that there is a reduced range of motion in the arms. For those concerned about breaststroke, the full legs feel great with a breaststroke kick. I experienced large time drops wearing this suit and I actually liked it more for this stroke than others. The reason I rated it 4 stars was this suit is not for everyone. I love it and most people do, but their are still those who would rather stick with speedo because of its popularity.
It is a very hydrodynamic suit; it glides flawlessly. Unfortunately, the high amount of polyurethane on the suit makes it very stiff and limiting. Furthermore, the PU insulates a little too well, and for distance swimmers like myself, the suit winds up being a hot box towards the end of your race. Overall, it is an excellent piece of equipment. I still prefer the TYR Tracer Rise, which I have had the pleasure of trying out. I believe Swim Outlet will soon put it on the market as product code 13278.
