Yes, it is a swift, and no that is not my equipment. That is Barry's Swift and 4 group
Rilley's coffee & Fudge from his Christmas party. The Mazzer is a Robur from our Titan Grinder project. The Swift is wide (think two Super Jollys joined at the hip) but the Robur is taller. Keep in mind there is a foot of space between them so a bit of optics come into play.
But in all seriousness, just pull two doubles. That is why machines have 3-way solenoids, you can pull back to back shots as fast as you can work. Or get a triple basket and pull two triples. I have never had need for more than two doubles in one drink and that is my rare latte so I cannot offer much more advice on the issue.
