Well, I decided to try a Duck last weekend, using the indirect method. All charcoals held firmly to the left and right with a nice clear area in the middle. Setting a very small draught from the base (one hole), with some Grand Marnier moistened wood-chips, we repaired to our local Tabac for an "Apero" while the fowl cooked on a low heat.
On egressing from said establishment some hour and a half later, it was hard not to notice the plume of smoke some 2KM to the north - reminiscent of GW1 and the Iraqi oil fires...
It's a long story but basically, we subsequently had a very nice dinner at our local restaurant.
