This guy’s called the Head YouTek Anion 135 squash racket. Or technically this is the second-generation of this racket so it’s the Anion2. Well, technically you should actually use a subscript 2, like this: Anion2.

The Anion2 is 135 grams, just like the the Xenon 135. But the Anion2 has strings going all the way down through the throat, whereas the Xenon has the crossbar. Here’s a picture of both rackets for comparison:
← Anion ← Xenon
According to the Head Website, the Anion2 is head-light and geared for power, whereas the Xenon is head-heavy and geared for control.
Also here’s the 2012 version, which was just called the Head YouTek Anion, without that pesky 2 weighin’ it down.
