I wanted to add that there's a good bit of bitter grapefruit as well in the flavor profile instead of just lime.

I made this with Rum Fire, which made the drink rather spicy and a bit medicinal. I like it, but I want to try this with other overproof Jamaican rums and see what changes.

I rate this as a 3.5 when made with ginger ale and just a 3 when made with lemon-lime soda. It's just my personal preference. I like the optional squeeze of lemon to cut down the sweetness. It's really good with pomegranate syrup instead of the candy sweet supermarket grenadine because the pomegranate adds some much needed tartness.

I have Rhum J.M. Blanc 55% and used that. Odd combination on paper but it works. I enjoyed it!
