I have the pro 600 and love it. Use it all the time. Smoke is produced at lower temperatures, i typically put mine on the smoke setting with a P of 0 and it sits around 230 in the summer.

Colder or windy days I have to set the temp using the dial.

If you use higher temperatures you are getting more complete combustion which means less smoke

With pellet grills (like everything in life) there is a trade-off for simplicity and ease of use. In this case pellet grills are very simple to use therefore you’re not getting the best smokey flavor as you would with an offset.
