Trust me, it doesn't fly like a heavy Z Comet when you get into the details. It doesn't have the excessive glide at low speeds which, despite my reverence for the disc, has always given me problems with ranging. It is much better in the wind and sits down much better as well. I can throw a high line with a Z Comet in calm conditions that gets to 375' without straining too much. I've thrown longer shots with Comets than any other mid. The Tangent is not like this. On a line drive it is slower and shorter than most other standard mids, making it almost a tweener/approach type disc. Though with a little air it can easily glide as far as most standard mids (not near a Comet though).
It is a disc that you put on line like a Comet. So maybe it's like a Comet that trades some of it's super glide for easier ranging and better wind performance. I really think the Tangent is something new in terms of discs, though the Comet is a good starting point for comparison (much better than discs like the Meteor/Fuse that people are wanting to compare it to).
I would say this is a very accurate post just on what I threw yesterday. In one word this disc is described as "smooth" imo. It doesn't turn or cut hard, it's very gentle in it's lines and line shaping. The glide is fantastic, but it's not nearly fast enough to push through like a comet. I will still carry a Z comet, there's just nothing that can hold the lines a comet can for as long as a comet can. My Z comet is pretty beat, so the tangent is quite a bit more stable on hyzers and flip shots. It's also more forgiving, pick up a comet if you want to fix your form over the tangent.
I'm actually really liking the compliment of the amp and the tangent. I can power down on the amp and have them kind of overlap on some turnover lines, or hit those longer lines that the tangent can't quite hit.
