Are you looking for something that is more angular and skid/flip or a ball that arcs to the pocket. If you are looking for angularity, the Rapid Fire Pearl, T-Road Pearl or Gravity Shift would be well suited to those lande conditions. If you are looking for balls that are more of an arcing motion, the Rapid Fire solid, T-Road solid, Hy-Road or Virtual Gravity would be good options.
In the Roto line up, the Pluto, Grand Illusion, Cell Pearl or Cell solid would be good options. Cell Pearl is most angular ball of course, but all 4 of these balls would work well on medium to heavy oil.
