A top weight of 4.7oz wouldn't make a ball visually wobble. Depending on where you put the CG, drilling the finger holes deep would help. Keep in mind, you can have up to 3oz of static weight in any direction, so your goal is really just to try to eliminate that extra 1.7 ounces. A good CG location, deepened holes and a weighthole should do the trick. But don't fret, if your pro shop guy is good he'll be able to find a solution.
