Venom shock or NU 2.0?

I’m a righty two handed bowler, throw about 15 mph.

I only have one ball which was my first ball ever, the raw hammer pearl. I’m looking at getting a new ball now that I’m consistently bowling and my technique is much improved.

I typically miss from having too much hook and hitting the left side of the pins. I great reviews about the Motiv venom shock and the hammer NU 2.0 balls. Would these be good for me, if so which one?
