id go with
-No Mercy Beat'n
-Raw Hammer Anger
-Black Widow Pearl
-Blue Vibe
people say get the cherry vibe because it has more backends, but it compares too much to the BWP in my opinion. i could be wrong but from what ive thrown with hammer, they are pretty dam close. the blue vibe however is a better ball for dryer lanes. not as much backends as the red one as stated by hammer, but still has the hammer truck like hit in the pocket. the beat'n is a great ball, but only when they have A LOT of oil. the anger and the BWP will be your go to balls. if i were you, id stick with the anger because ive heard the BWP has SOME over under reaction. so that and you cant forget about..
-Black Widow Spare Ball =D
Just looks so dam cool!! =P hope this helped!
