I have 2 bone in shoulders waiting for my break in smoke on the Traeger Texas I got. I have the Digital thermometer but have not installed it yet, so I will be using the 3 speed switch that came on the unit. I plan on smoking them on the Medium setting but an not sure how high that goes, during the season process i found out that high was 450 degrees according to the gauge on the lid. How long do you anticipate the Butts will take to finish for pulling? I just need to make sure I start early enough to finish about noon.
