Think about time and the effect on fresh flavors.
How long is your oven cook,and how much air do you flow over the parts?
Put all fresh herbs/vegetables on a 20 lb packer,load 'er up with hickory, and cook it for 24 hrs.
Want to bet me,you can pick out the individual seasonings?

I use a CS 160 down here,hickory chunks,a bottle of wet allspice berries in foil,and have lots of Island diners/cooks/experienced tasters eat my poultry/pork/fish.
I am king.
Of course,I give away plenty of cheap island rum and Red Stripe beer.

Just a couple thoughts.
