timfuller,
I have also read that cooling the wort in the boil kettle allows the proteins in the hot break to dissolve back into the wort..
I have never read that. I bet it's just a "I wonder if supposition?" I have IC'ed in the past and now only no-chill. My beer (if in style) is as clear or clearer and anyone's. So, since my beer slowly cools than the proteins should be back into my wort? Not a chance! Cold break forms at about 140F. The Irish moss (or whatever) and the 140F cold break clears my beer perfectly.
If you like to use a copper coil or now a stainless steel coil, than do so. If you want to use no-chill and not use the IC than do so. The beer will be clear as long as the proteins are broken up by a long and vigorous boil and proper pH values.
