Never had a Flathead in a lancero-ish size, I usually keep a few of their Sparkplugs in stock though. So far it's got a bit of a restricted draw on it, rolled super tight. We'll see.
SOL chelada is best chelada, just FYI.
Reporting back, post smoke. It wasn't anything to write home about, but it did pair decently enough with the tomato spice of the chelada. I don't think I'll pick up any more, though.
