Build a 3-6 ball arsenal with only one company, but have 2 separate arsenals that you do NOT allow to intermingle. Storm/Roto, EBI, Motiv, Brunswick/Radical/DV8. Essentially owning 6-12 balls. This derives from a recent itch to build a Motiv arsenal, while maintaining my Storm/Roto arsenal. Rotate weekly or be forced to choose which arsenal to take to tournaments. If the cash is there and you want to add another facet to the whole thing called bowling.
