That looks pretty good. I’ve always seen it made with some variety or combination of aged rum, usually demerara. My personal favorite for this (and most tiki drinks) is Hamilton Jamaican Black Rum. Using white rum might be the right call for serving it with dinner.
I think you could turn just about any Jungle Bird recipe into a decent batch cocktail. Most of the ingredients are pretty stable. The juices would go off first, but not likely over the course of a few days. If you need them to sit for more than a week, then you probably want to look at something with spirits only.
I’m not much help on the specific question, but I hate to have it die on the vine. So, I’ll offer what advice I have.
I know a couple of people who shop at DXL and I’ve heard them recommend it to others, so I’d check with what they’re offering. The guys that I know that shop there dress well.
The other place I’d look is Bonobos. They’ve got a wider selection of sizes than most retailers and I’ve been happy with everything I’ve bought from them.
