Syrups vs infusions

The specific situation is that I want to make some hibiscus margaritas. I intend to make them Tommy's style (i.e. without triple-sec/orange liqueur) for a cleaner flavour.

What is the best option?

1. Infuse the tequila with hibiscus and use simple/agave.
2. Make a hibiscus simple.
3. Both.

I know that hibiscus can lean towards tart but, generally, what is the consensus?

(Bonus round: anyone have some tried-and-tested specs for either 1 or 2? I am using whole dried flower, rather than 'tea' bags.)

Thanks!
