What Traeger grills have Super Smoke

[RickCrosser]

I'm looking to upgrade my Traeger gill and would like to know what series have the Super Smoke option and is it worth it to have that feature?

Ironwood and TImberline, Pro doesn't. I like it. Many say the new models aren't as smokey. Can only use up to 225F.
