I did performance tests on 5 different balls, from 3 ranges, with 2 different barrels. I recorded info on hits, barrel breaks and wingers. I shot 15 shots for each combo, 5 warm up shots to establish range and accurancy, and then recorded the data on the following 10 shots.
These balls had 5 breaks and no wingers during my tests.
They were more accurate in the Thunder Pig by a measurable margin.
All teh breaks were in the Thunder Pig.
They hit 10 for 10 at 20, 7 for 10 at 30 yds and 3 for 10 at 45 yds through the Thunder Pig.
The numbers were 10 at 20, 4 at 30 and 6 at 45 through the Flatline.
Weaknesses:
There were a high number of breaks, but all were in the Thunder Pig.
Conclusion:
Pretty good ball, but a high number of breaks during my testing.
