Back in my "BBQ" dark days (gasser/unmodded ECB) I was never able to get good smoking w/ chips. I used many different vessels to hold them in...soaked, unsoaked, didn't seem to matter.
Now that I'm using "operational" smokers & kettles (and me being a much more knowledgeable smoker, due to this place!) w/ charcoal & chunks, no problem.
