Dave, your Cherry is drilled significantly different from your Emerald too, don't forget that.
As for the Emerald between the SC and SD...yes it will fit but I think you would be better served to look into something like a Blueberry (if you can locate one) or a Black Cherry Bomb as soon as they are available (another 2 weeks I am told).
What you have is a skid/flip pearl reactive and a roll/arc particle. The perfect fit in between is a solid reactive or a pearl particle.
The Pearl Bomb is a great ball if you have oil on the heavier side encounter carrydown. It is particle pearl and will smooth out your breakpoint and continue thru some moderate carrydown.
The Cranberry will be a replacement to the Blueberry and will have a slightly modified core from the BB. They are still testing this ball and are unsure of exactly how it will be designed.
The Black Cherry Bomb will be the best all around ball made (in my opinion) as long as it is not TOO strong.
The Cherry Bomb pearl may also work for you since it is inherently stronger than their other core designs. The ball will handle a decent amount of oil but doesn't like carrydown much.
If you can locate a Blueberry or the older version, the Black Raspberry, it would serve you well as they are probably more versatile than the others mentioned.
Best of luck and feel free to email me if you have any further questions.
