do these two balls complement eachother in any way, or are they two similar as balls that go longer with powerful backends. i currently have a attitude which i love, but as i now bowl on a second shift, i am seeing inconsistent results. most of my weeks look like this 250_230_170 as i get more and more carrydown and the lane gets drier in the mids. obviously a drill and cover change can force these 2 balls to react differently, but i am looking for a 2 ball arsenal and looking for a complementary ball
