correct, they were long, and they were discussions, but I'm not sure that anyone has successfully "discredited" mr. power cranks claims. just as I'm not sure Mr. powercranks claims are valid. I do know folks who swear by these as being a very instrumental tool for their own individual improvement, although I'm not so sure the improvement wasnt related to the training they were already doing regardless of using the powercranks or not.
Summary - powercranks are very spendy, their usefulness is debatable, spend your money on zipps.
