@BG1 I've found the higher the temp I cook the less smoke flavor you're going to get.
Really anything over 300 and the smoke flavor is not very strong if at all. So try smoking at a lower temp then cranking it up to finish.
A reverse sear makes amazing steaks. Smoke at 225-250 for an hour or two then remove the steaks. Crank up the Rec Tec to 500 and then put the steaks back on for a couple minutes each side and remove and let rest for a few minutes.
