Foiling speeds up the cook by braising the meat. Smoke does no longer penetrate so it really makes no difference if you do them on the WSM or in the oven. The one drawback in foiling is the bark gets soft, so taking them out and back over coals for a few minutes is often done, or foiling with enough time for an additional 15-30 min in the WSM to set the bark a bit.
