I have the CC SG24 WIFI which has a PID controller similar to the Woodwind. I usually get a decent amount of smoke out of it on the low smoke setting. The buckboard bacon I did a few weeks ago, I ran just a smoke tube with the grill off until the temp in the grill started getting up into the warm smoking range ( it was fairly warm that day and the tube was generating enough heat by itself to get the temp up too high).
Once the temps got up too high, I started the grill on low smoke setting and warm smoked the bacon to 145*. Everyone who tried it thought it better than store bacon. I got another one cured up and drying off in the fridge and will smoke it in a day or so. The first one was just salt, cure#1, and brown sugar. The one that just finished curing also got a dusting of coarse black pepper and granulated garlic, so I'm anxious to see how that's going to taste.
Edited to add: I used about a 50/50 blend of Lumberjack 100% hickory and 100% cherry in both the tube and the hopper.
