Greetings,
If you had a Rubicon and a Afterburner what two ball would you add from the Storm/900 Global ball line ? There's a demo day coming up and I want to add the missing balls to my bag.
Thank you

Depends on what you want the ball to do and how much hook you are looking for.  But without knowing anything; I would go Trend 2 and Hyped Pearl.  Another popular choice I am sure is going to be the RST-X2.

I would look at the Zen. It will fit between the 2 you already have and it is extremely versatile. It might eliminate the need for another ball.
