I like the Easton Incrediballs. They're durable and the weight is closer to a real ball. Lite Flites are too light -- tough to throw. Haven't really used the Softies.
I like the Jugs Softies A LOT more than Incrediballs. Softies are or feel like leather. Incrediballs get slippery very quickly and they get mushy much more quickly. We use real balls in the gym whenever possible and whenever allowed.
