Good Show !!!
Glad it worked out well for you........
This is what your basic "thin blue" smoke will want to look like ~~>
That indicates a small, hot, clean ~ burning fire......
The foil packet works pretty darn good for chips also......just use a double thickness of foil, a fat fistful of chips, fold it up fairly tight, leave a little play inside the packet & poke 3~5 small holes in the foil to let the smoke breathe out....
That will work fine, loose or packet, for chicken & say, appetizer type stuff; if you're doing larger pieces like pork shoulder or roast type thing, go ahead & commandeer some chunks........
