Honestly one of my faves, it's fairly straight with a little drift at high speeds and it glides forever. Fairly small for a 10 speed so like a PD, its more comparable to a 9 speed.

This disc has been a workhorse for me since it came out.  This disc is very straight for most of its flight, before a late reliable and hard fade.  It is not some insane beefcake, but does not flinch in the wind either.   This disc being a 10 speed really makes up for its lack of glide, it gets where its going fast, then fades right near the end of the flight.

My Disc: 172g K1 Hard Malm Tour Series 2025

Most of the other reviews are spot on. I agree with the 10-speed teebird comparison. On a good throw, this disc holds straight for awhile before a nice fade as it slows down. In my short experience, this disc doesn't quite hold up in wind. I think maybe because the nose on mine seems a bit blunt compared to discs of similar speed.

I will use this as my summer distance driver with my slower arm speed and I would recommend it for that use case. A distance driver you don't have to completely rip to get a proper flight with nice glide.
