Brilliant, the combination of both tequilas makes a really great cocktail. For my personal taste it was a tad on the sweet side, so I suggest to be reluctant with the agave syrup.

As it turned out this variant is so far my preferred one. I did play with its basic idea a bit further and add 0,5 cl smoky Mezcal, 0,5 cl Amaro Averna (works always well with citrus fruits and substitutes here the Margarita Bitters) and did replace the agave sirup with Mastiha liqueur (which aromatic profile IMO harmonises well with agave based spirits).

Living in San Diego and on the border with Mexico, we have a lot of different margaritas available.
This was excellent. The combination of the two different tequilas allow the citrus to shine. This is a very refreshing margarita and perfectly balanced. Worth a try.
