"want good racing or hi-tech " trouble is in auto racing, they have learned 'how' to go much faster than one can safely go around the turns. In the old days, when getting a bit more speed helped you win, it was easier to design both cars & rules.

In swimming, we seem to not be to that limit yet. Perhaps we will need pro & amateur categories, where sponsors can outfit their teams with the highest tech suits, and damn the cost.
