When my Weber bullet bit the, well, bit the bullet, I didn't replace it. I get stuff started on a Weber kettle with offset heat and wood chips/chunks for a few hours then wrap in foil and finish in the oven. I feel like I get the smoke I want, then I retain moisture and control heat. Obviously the quantity is limited, but if I need a bunch my baby bro will do it for me. I don't expect to change the minds of any of you cave men, but it does work well.
You certainly can over-smoke things. I have, and it's nasty. I wonder about the Traegers in cold temps burning a bunch of pellets to keep the temp up, but I'd bet you can tweak something in the process/system to prevent over-smoking.
