I bought an all copper CFC off ebay. The wort line is 3/8" and saw where some people using a pump, whirlpool back into the boil kettle. After whirlpooling and cooling the batch then go to the fermenter. Will I be able to get a whirlpool with 3/8"? Other than keeping the break out of the fermenter, is there any advantage to cooling the batch and whirlpooling like this? Do most of you using a CFC go straight to the fermenter w/ the break? Thanks
