yep, just do it. I use the standard counterflow chiller -> copper tube inside a garden-hose design. No convoluted tubing. One great hint is to smear vaseline on the outside of the copper tube, else it is extremely difficult to stuff all the tube in the hose.

The wort is within a few degrees C of the water temperature. Forgot the exact numbers, but way below max. pitching temps. You don't need to get any fancier than this unless you want to get higher flow rate. From memory, I used the smallest copper tubing I could find (would have to check what size it was). This makes my flow rate rather slow, but lengthens the time the wort is in the copper tube.
