need a ball to fit between VM and Mojave...thinking Damage or Karma Pearl

I'd probably look at the Damage.  The VersaMax should be slightly stronger and the Mojave will give you the least flare. 

Originally I had thought a Massive Damage, but the VersaMax is going to be similar to where it probably would not be the best choice in filling the gap.

Thanks guys...my MOjave gives me a urethane like like reaction with massive hit, so that is my ball for really dry. Need something to handle lighter conditions. My versa Max is drilled with a 5'' pin to pap and handles med/light really well, so needing something to fit between the two.

I would go with the Karma Pearl. Drill it slightly weaker than the Versa max and you will be good. You could also look at the Slingshot, but that may be a little close to your Mojave.

The Karma Pearl with a weaker layout would be an excellent choice.
