There is nothing wrong with wrapping either. I do it both ways. I am not a fan of the 321 method as it overcooks them. Wrapping can impart flavor you dont get with cooking naked. Especially if looking for that sweet profile but you lose a lot of the rub profile. I cook mine at 250. I dont concern myself with temp jump on the stick burner just roll with it. It sounds like you are having an airflow issue. Keep the exhaust fully open and adjust the inflow openings to moderate the temp. When i add a new stick, abt 2” - 3” diameter, i will crack the door for cpl minutes so it ignites. I also keep a cpl sticks on top of the firebox so they heat up and sometimes ignite before putting in the box. The IT temps and probe tests mentioned above are spot on . Lots of different ways to achieve success. Just have to find what works for you and your smoker.
