I threw 2 total Nv's one with the ( recomended drilling ) and one with the ( Do not drill).
my axis is 5 over 1/2 up tweener with 275 revs
ball A, the recomened drilling had way to much hook for me and to much backend reaction. line played 20, to 12
ball b, do not drill worked really good for me good mid lane reaction strong arc/flip reaction. 17-9
