I know you said 2 or 3 softies with various stripes, what about a spinner? We have a new PC who is very adamant about using a spinner! I know striped balls work, but a spinner don't lie! They sure can be a pain though! We've always used striped balls and avoided the spinner like the plague but I'm finally coming around and seeing the benefits of using one.
I haven’t spent a lot of time with a spinner and should probably play around more to see if there is anything I’m missing. I don’t like the way they feel in the hand and they really limit grip options. I don’t care for the way I see most PC’s use the spinners. The drills just don’t translate well to real spins with a ball. They might be good for initially teaching people spin recognition, but it’s not that hard to teach pitchers, catchers, parents and coaches what good/bad spin looks like. It amazes me how many folks don’t know the difference.
