Skinfit, and it's speed in the pool

I’ve been looking at Skinfit (www.skinfit.at) for their one-piece tri “speedsuit”.

It says on their site it’s great in the pool, with guaranteed swimming improvement.

I’m full aware that proper technique, and practice will improve my swimming more than a suit, but I do race in many short events where every second counts.

It’s got a rear zipper (like a wetsuit), and particularly flat seams. Any opinions? Is it like fastskin, aquashift in any way? I saw a lot of european pro’s wearing them at Kona as a oversuit for the swim. Worth it?

You know the answer to that.
THe difference between that suit or a normal suit is minimal, especially to the average swimmer (assuming you are).

If not,

your probably so good that its going to show minimal improvement as well.
