I already have a rico'd sanded mammoth as well for smooth on heavy oil and a sidewinder with a 4" pin to PAP.

If I have the C-system 3.5 what ball or balls would you recommend as a next step down to fill the gaps under the 3.5 and after the Sidwinder..... ??

Wildcard , Diamondback, Wild Ride, Rattler, or Python

I hear good things about the Wildcard but that may just be too strong and give me 3 really strong balls.
I'm thinking diamondback and rattler. Or maybe Wild ride and rattler but then that is two pearl balls..
