Hi. Tried out the Zooka ZS740 yesterday.
Pertty cool. Quiet! Real baseballs not very accurate so I may return it. It spins the balls which is good. But sometimes they're all over the place. Like one pitch can drop a foot in front of home plate. Hit the ground. The next pitch was high and outside. Now that's horrible! Then the next pitch can be in the strike zone. Just not consistent. Dimple balls much better but sometimes out of strike zone by many inches and then in strike zone.
Fun tho mostly.
My bat is a 34" Easton. -5. What does -5 mean? Is that good?
