Dougb, Yes the Slingshot would be a stepdown from the Ringer. You may be able to avoid buying 2 balls, if you get the Ringer and just drill it a little weaker. This way as the Versa is too much, you can move right with the Ringer and beginn chasing the oil again. If you truely see blown apart conditions, then having a Slingshot in your back pocket would not be a bad idea. Around here, I hardly see enough friction that I need to always have the Slingshot. I mainly take the Slingshot when I bowl on shorter conditions.
