Yes, I've tried both the 16g and 17g versions, which I got from a local PK sponsored player. Strung up a hybrid with IQ Elite in the mains for myself twice and a friend once. The stuff looks like Lightening XX with the metallic wrap giving it a "flashy look", but it's a multifilament which Lightening XX isn't. Playability was like most other multi's, but the durability was nonexistant. My two tries broke within the first half hour of use. My friends lasted two days. My fourth try (with the last half set) has lasted two outings so far. We'll see how long that lasts. In summary: Playability - what you'd expect in an expensive (>$10) multi, durability - nada.
