Woody123 - one thing you need to be careful about when using the RevFire is that it only measure the rate of spin per second and NOT the DIRECTION of the spin (e.g. 12/6) or the LOCATION of the pitch which is very important in developing the correct movement. For example, your DD's curveball could have bullet spin and still register 20rps but have very little movement because it's not 3/9 spin.
The other interesting thing about the RevFire is that a change-up might register similar rps as the fastball but it obviously takes longer for a change-up to reach the catchers glove. That reading threw me off the first time my DD threw her flip change and it registered 17rps on the RevFire.
Lastly, while I like the RevFire, after using it for about a month, DD pitched in a tournament and was very wild especially the first two games. She was wondering if the weight of the RevFire softball might be different even though the company states otherwise on the specs. I chalked it up to her just having a bad day but she hasn't used it since. Need to weigh both balls tonight to see if there is a weight difference (or maybe noticeable seam or leather difference?). By the way, she normally practices with the Worth Dream Seam.
