My opinion is you may be better off adding a ball that fits more in the middle of those 2 you already have. Both the Nano Pearl and Taboo Blue/Silver are still going to be heavy oil balls, albeit with a little different motion than the original Nano, but very comparable in overall hook.
I would recommend looking at a ball like the Epidemic perhaps, going to get good length with pretty strong overall hook, but when in terms of the Nano, will be more skid flip when the front of the lanes burn out but you still need the angle the Onyx Vibe may not provide. Also, the new black magnetic core really provides some extra energy at the pins that most others do not. Impeccable carry.
