So, summer is here, it's hot as fuck, and I am about to finally get my cigar on. Makes me think, I want to sit out on the back porch in the evening and take in my classic Cuba Libre and stogie. I've never been fancy here, because outside of nice watches I've always been a degenerate loser who drinks cheap beer and falls down. But, in the spirit (lulz) of my newfound baller status, I'm trying to class the classic up. Guy I work with swears by adding a splash of vermouth and a lime, because when added to the coke and rum it becomes magical and really ups the game on this most simple of drinks. But he is mostly an idiot so I do not fully trust him here. Plus, what the fuck do I know about Vermouth anyway? Sounds classy. So I need advice.
Welp, I KNOW this place has game when it comes to drinking good shit, so help me out. What's your recipe for adding some zip and panache to the old classic Cuba Libre?

I am normally a Bacardi guy, but open to suggestions across the board on how to have a rock star rum based summer stogie pleasure experience.
@Dennis_DeYoung you better weigh in here
