.... I just did a search for this topic because after two seasons of racing, my Pro 5.0 is not working well. The spring is worn out most likely,, It doesnt come back to the left and just doesnt have the tension it used to to keep it in center. I have been shifting from 3rd to 2nd at the track....which I had only done twice ever...ive done it the past three out of five runs.... have to be real careful now... I am debating whether to get another pro 5.0 because i think they should last longer. What about hurst? I felt one in someones car and it seemed real nice.
