JustinWi asked all the questions I would.
I'm also sorry to hear yours isn't working out for you. Mine is unbelievable. Before I'd write Motiv off the map for your arsenal can you give us details on how it was drilled, what's your PAP and the details of how you bowl like he asked?
I'm not saying it's the drilling, but in my path of learning what my game needs I've gone through at least 3 or 4 balls that should've been beasts (black widow bite, Seek & Destroy, NVS) that all wound up being duds because the drilling was incorrect for my game.
I've been fortunate enough to own the GT1, SX1, TX1, SR2 & QZ1 and I've had great success with all of them.
Best of luck to you with whatever equipment you throw.
