They don't look done to me, you foiled em because they were at temp, don't do that get them looking how you want then foil, it depends a lot on the weather on my wsm some times they never even get foiled. If your not using a good thermometer too? I use themoworks fast as hell and accurate. Pay attention how the prob goes into the meat on a butt the probe will resist at first because of the bark then be like butter.
