Hello everyone. Well it's official....I threw away my electric smoker after 7 years and ready for a wsm! The electric did me well but never achieved that true smokey flavor. My first decision is on which size to buy. I'm single but would like to eventually host a few parties up to 15 people. The majority of the time I'll be cooking for 2 or 3. Should I purchase the 14.5" and upgrade later or buy the 18" now? Any ideas would be great!
