Hi all, first time poster here and first time smoker. Thinking of buying a WSM 18.5 or 22 but first needing to justify the 22 as I will mainly be cooking for 2-4 people 99% of the time. What do you guys think? Also for additional equipment I am thinking a wireless temp probe and also a WSM jacket from Bbq guru as I will be in negative numbers half the year here In good ol Wisconsin. Is there anything else needed? Any difference in opinion? I am thinking I will be using the minion method do I need additional equip for that?
