This was what Dave Dunipace said on the PDGA board about them:
From the sounds of it, it might actually be the disc the Groove was supposed to be.davei wrote:So far, the Pro Katanas look pretty good for distance challenged throwers, hyzer flip at less than max power, and power rollers. Power rollers can throw flat to slightly turned over and let the disc do the work. Power throwers should probably pass on this disc except for specific uses such as high turnovers and rollers.
The Katana in all three plastics tested so far is more speed sensitive than all of our other high speed drivers. This basically means it will flip considerably more into the wind than down wind. The R-Pro Katana is flippier than the R-Pro Boss and flippier than the Pro Katana, so it probably won't go into general production. The relative wind speed sensitivity makes assigning a turn number a little challenging, but for 400+ft throwers the turn for Pro will be at least a -3. For 350 ft max throwers, the turn will be less, (except into a wind). And, I don't recommend throwing these into a wind. Tentative flight numbers are: 13, 5, -3, 3.
Testing of normal Champion was unimpressive, compared to Pro, but the addition of the stabilizing process might change that. Though we haven't tested it in Starlight as yet, I believe that will prove successful.
