Give them all some throws and do a quick write up. I'd be interested to see your thoughts.
Of those 3, the 166 champ would appeal most to me as well.
I didn't have a chance to get out until 15 minutes prior to sunset last night. So I pretty much just got 3 throws per Katana, plus 1 throw with the new King. Also didn't have time to measure throws, so my first impressions aren't real accurate. That being said, here's my initial thoughts --
Thrown with hyzer:
King - easy max distance line (flipped to flat then kept turning, then had a healthy fade and finished straight overall). It clearly was the most unwieldy of the fresh discs, so although I was impressed by the first throw's flight I didn't want to risk losing it in the dark. Hence why I only threw it once.
162 Pro Katana - Started fading early. It did seem to fade forward much more than other Speed 13+ drivers, which was encouraging and made the distance loss less pronounced.
162 Blizz Katana - Flipped to flat. Ate up some good distance (closer to the King than the flat Pro Katana).
166 Champ - Faded early, similar distance to the flat Pro. But seemed to glide out better, which meant it actually ended further left than the Pro.
Thrown flat:
162 Pro - Really no noticeable turn, even thrown flat. Did chew up some decent distance despite that.
162 Blizzard - Healthy, but controllable, turn. Significant forward penetrating fade. Seemed like it went pretty far but again I wasn't measuring. Finished about 30'-40' left of target so clearly more fade than I gave it credit for.
166 Champ - A glidey hog. Thrown flat I could tell the 166 Champ clearly starts fading earlier than even the 162 Pro. But it's not a "seek the ground quickly" kind of overstable, rather it's a "fade for 50% of its flight" overstable. Not sure what I think about that.
I threw each disc flat a second time and found pretty similar results.
Surprisingly, I most enjoyed the Blizzard Katana. It flies out-of-the-box like I expected Shrykes to. I've got a pretty full plate this week, but hopefully I can find time to sneak outside and do some measurements. Also interested in seeing how these discs fly when forced over a bit, and when getting enough repetitions to develop consistency with them.
For reference, I'm typically a 320' straight-to hyzer and 340' full flight kind of arm. Most of my measured throws (meaning the disc went far enough for me to warrant the effort of measuring) are in the 375' range, but that is a full send plus luck for me.
