As mentioned above, if you want to match your specific Ezone 98 to a specific DR 98, you will absolutely need to measure the specs of your racquet and adjust accordingly based on your target specs. SW can vary widely between different racquets of the same model.
If you just wanted to add 6-7 to your SW and add 5 grams of static weight while basically maintaining the same balance, 2 grams at 12 and 3 grams under the butt cap will get you close.
