Making gin in a reflux still

Hi folks! I would try to make some gin with my reflux still. I firstly do a spirit run, proof it down to about 50% and then filter it. Proof it again to about 40% and then fill it into my boiler. I will remove the copper and place a muslin cloth with the herbs in my column. My question is, should I run cooling water through the dephlegmator, or only through the condenser?
