I'm going to be making this today trying the rum split to see if it will work. I already do a split base of Goslings and Smith and Cross with my Hurricane recipe so I know the two rums play well together.

Hilarious name, I have to try this.

I would cut the mint leaves down to 8, and try Smith and Cross with Wrap and Nephew to add some depth to the drink.

I would do 2 ounces of Goslings and something like half an ounce of Smith & Cross, would give that funky nature in the name and not be as sweet especially since it already has Grenadine and Simple Syrup.
