In a side by side ball test we did at the factory, both balls picked up a heavy roll at about the same length, but the Goliath was more continous on the back end and the Swamp ran out of energy. It also seems like the surface of the Goliath is a little easier to tweak. It really has the ability to create a great look on certain conditions, it's just that most bowlers or ball drillers are a little hesitant of the medium to high load particle balls.
