On medium lane conditions, you could probably get both balls to work. I would drill the Black Cherry Bomb CG axis with a 4" pin, under the ring finger, hole on your axis. This will tame the BCB down a bit, making it more versatile on different conditions.
With the Cranberry, I would go with a CG out leverage, i.e. 4 1/2 x 3, ending with a 3 to 2 ratio top to side. This will make it fairly strong and controllable. Adjusting the cover on this ball can do wonders. =:^D
