Bowling ball line up

[IIIIYummyIIII]

I am currently owning a storm virtual gravity, track 505a and a spare ball. I am looking for a ball with more of a back end that rolls down the lane more, but i don't want the ball to be similar to my virtual gravity. Any ideas of which bowling ball i should get? I was thinking of a track 920a.

Track definitely has enough on the back end. I dont use it for that reason. You might want to look at Morich too.

If you're looking for under the Virtual Gravity, then I'd probably say the Hy-Road, C-System 4.5, or Bedlam.
