I use a rectangular cooler with a braid. Works really well and, after a few reps (increased sparge temps and stirring was the key for me), I am getting 75-80% eff.
I try to drain the tun dry every time (double batch sparge). Towards the end of each sparge I get bubbles in the drain hose as if it is sucking air into the braid. Of course draining it dry results in more bubbles than if I simply stopped when I first started seeing bubbles. I suspect if I stopped I would leave about 1/2 gallon of wort in the tun.
Neither I nor any of my more "sophisticated" taster-buddies have noticed any off flavors in my beer. Still, I can't help but wonder if this is something I should try to eliminate.
Any thoughts?
